409 Stainless Steel Sheet and Plate Suppliers

409 stainless steel sheet suppliers

Stainless Steel 409 sheets are well known for their resistance to exhaust gas and atmospheric corrosion, boasting excellent tensile strength. Arc welding processes can easily weld this ferritic grade but preheating prior to welding must first occur.

Champak Steel and Engg. Co is one of India’s foremost suppliers of SS 409 Sheets and Plates.

Résistance à la corrosion

409 stainless steel is an all-purpose ferritic grade designed to resist corrosion at higher temperatures. While primarily utilized in automotive exhaust systems, its formability and weldability has expanded its applications to cover industrial equipment. Furthermore, this non-magnetic alloy offers resistance against sulfur dioxide and nitrogen oxide corrosion as well as being non-magnetic.

Type 409 steel offers excellent resistance to sulfuric acid and other oxidizing acids at elevated temperatures, making it a good choice for chemical processing applications that expose it to strong corrosives. Furthermore, its corrosion-resistance makes fabrication straightforward; you can cut, blanked, stretch formed and drawn without difficulty; its formability characteristics resemble carbon steel’s formability characteristics.

Alloy 409 is a heat resistant ferritic alloy composed of chromium stabilized ferritic metal with increased resistance to oxidation and corrosion compared to carbon steel. The presence of chromium helps prevent pitting corrosion as well as surface damage such as pitting. Furthermore, titanium and niobium enhance its high temperature degradation resistance.

This grade boasts superior oxidation resistance compared to coated carbon steel and Type 410; however, its resistance falls short of Types 304/304L and 316/316L and should not be considered decorative or surface critical applications as it will oxidize when exposed to atmospheric conditions, eventually developing light surface rust.

Stainless Steel 409 sheet can be found both hot rolled and cold rolled forms, in various finishes, making it suitable for automotive exhaust systems and other durable equipment that requires durability. Penn Stainless stocks Alloy 409 in many shapes and sizes such as sheet, plate, coil bar & rod processed flat bar tubular products to meet all your specifications for this grade.

High Temperature Resistance

If you require stainless steel that can withstand high temperatures, 409 is an excellent ferritic choice. With excellent oxidation resistance and welding performance, 409 makes an excellent option for automotive exhaust systems or petroleum equipment applications as well as non-automotive ones like home heating systems or fuel filters. Plus it boasts superior corrosion resistance when compared with carbon steel grades!

Chrome in 409 stainless steel helps protect it against corrosion and oxidation, as its presence helps deter both. While chromium can be found naturally, for industrial uses it must first be extracted from underground deposits before being processed through an electric furnace and formed into slabs by rolling mill. Once reduced in thickness mechanically it can then be sent on its journey. Ultimately sheets or strips may be produced and processed further for use.

Given its moderate tensile strength, 409 can be welded using most welding processes such as gas shielded metal arc, resistance spot welding and gas tungsten arc (GTAW). Furthermore, 409 offers excellent protection from atmospheric corrosion.

409 stainless steel may not be ideal for decorative applications, but it performs admirably when visual appearance is not key. This grade can be found in automobile exhaust systems such as manifolds, catalytic converters and mufflers as well as industrial equipment and truck exhaust systems.

409 stainless steel stands out among its peers by having superior resistance to sulfates and chlorides; however, its organic acid resistance is lower, and it may lead to some forms of exhaust gas corrosion.

SS 409 is an economical choice that is suitable for many purposes, from corrosion resistance and welding, to excellent forming characteristics and cost-efficiency when cold worked. It offers excellent corrosion resistance while remaining cost-effective and providing good ductility – ideal for applications that prioritize cost and ductility simultaneously.

High Strength

Stainless steel 409 sheets and plates are widely respected for their ability to withstand corrosion, boasting high tensile strength and withstanding temperatures up to 675 degrees Celsius while also resisting pitting and corrosion. As an excellent corrosion barrier, SS 409 Plates can be found used in environments where durability and reliability are key, including automotive industries where components must withstand extreme heat levels as well as environmental challenges. They come in various sizes and thicknesses.

SS 409 is an economical stabilized ferritic stainless steel with excellent corrosion resistance and formability that’s well suited to mildly challenging environments, making it an attractive alternative to carbon steel. Ideal applications include automotive exhaust systems in which aesthetics aren’t as important, oil equipment and gas turbine exhaust silencers as well as farm equipment.

This grade of austenitic stainless steels is comparable to its austenitic counterparts, yet offers improved oxidation and corrosion resistance at elevated temperatures. Weldability is excellent and complex shapes can be formed without losing their ductility; additionally it resists chloride stress corrosion cracking as well as crevice corrosion; thus making this material an excellent choice in environments containing high levels of moisture or gases.

Chemical and abrasion corrosion-resistant aluminum sheet is widely recognized for its superior formability and versatility, featuring easy cutting, blanking, stretch forming and welding processes; in addition to cold working and annealing without losing corrosion-resistance properties.

Penn Stainless offers not only standard products, but also offers an array of specialty services including forming, cutting, shearing, slitting and packaging; non-destructive testing services; custom orders to meet customers’ unique requirements and non-destructive testing; packaging services as well as non-destructive testing services – and much more. They can handle jobs of all sizes and complexity with ease!

Excellent Weldability

SS 409 is an outstanding weldable grade, accommodating most common welding techniques including high frequency, resistance, gas tungsten arc (GTAW or TIG), and gas metal arc (GMAW or MIG). Autogenous welds may also be performed successfully to produce strong welds that resist stress corrosion cracking while remaining ductile after welding.

409 stainless steel’s excellent corrosion resistance and formability make it an excellent choice for many industrial applications, from automotive exhaust systems and truck spreaders to agricultural equipment and heat and gas turbine exhaust silencers. It can withstand extreme temperature ranges while remaining formable; thus making this material particularly versatile and useful for applications requiring greater oxidation protection than carbon or coated steels can offer. It is often found used in automotive exhaust systems, truck spreaders, agricultural equipment as well as heat and gas turbine exhaust silencers.

As it is susceptible to mild corrosion, this grade is not advised for decorative applications; however, this issue can be overcome through adding appropriate amounts of chromium and titanium. However, this grade is an exceptional titanium stabilized ferritic alloy which combines excellent elevated temperature corrosion resistance with medium strength and formability; particularly suitable for exhaust gas environments and lower atmospheric corrosion resistance than its 304 counterpart.

As with other ferritic stainless steels, this grade may not compare as favorably to austenitic grades for high temperature resistance; however, its fatigue properties and good ductility allow it to still be utilized in mildly corrosive environments. Furthermore, sulfates and chlorides corrosion resistant.

This grade of stainless steel offers an economical solution for applications requiring corrosion and oxidation resistance, such as complex shapes. It can easily be formed into complex forms and endure conditions that challenge other grades of stainless steel. Furthermore, this material can be readily welded for weldability applications, while chemical corrosion remains minimal compared with its peers. Fabrication and machine work is made easy while heavy forming or bending are best left for other grades of stainless steel; preheating prior to welding should also be performed for best results and postweld anneal should occur postweld for optimal results.
