Stainless Steel Sheet

This stainless grade is typically purposed in appliances, food service equipment (cooking utensils, sinks, restaurant kitchen tables, and shelving) as well as for architectural applications like window trim, doors, and trailers.

It is an austenitic steel with magnetic properties when cold worked. It has high toughness at lower temperatures and exhibits good strength. It is weldable and able to be bench formed and roll formed. It is not hardenable by heat treatment.

This limited number austenitic steel grade is intended for subzero temperature conditions. As temperatures decrease, this stainless steel grade increases in yield and tensile strength. This makes for excellent use in liquid oxygen tanks and accessories as well as liquid hydrogen handling equipment. It can also have structural applications, as in bulk transport equipment and truck trailers.

301 shows high strength and excellent corrosion resistance. It is used in a wide range of applications including structural parts for aircraft, architectural and automotive trim, vehicle wheel covering, trailer bodies, cooking utensils, drainage, sinks, and appliances. This grade achieves high strength by rolling and will lose less ductility than other similar stainless steel grades. To optimize corrosion resistance, this grade should be cold worked in the annealed condition.

304 is one of the most popular stainless steel grades as it demonstrates high strength, excellent corrosion resistance and outstanding formability. This grade has lower carbon content, and is very ductile. It can be cold worked by roll forming, deep drawing, and bending. This grade is suitable for forming complex shapes. You’ll see this grade in the oil and gas industries, as well as in the food service industry.

304L is an ultra-low carbon variant of 304. It is often preferred over 304 stainless due to the fact that it is less susceptible to intergranular corrosion. However, in other mechanical property comparisons 304 will outshine 304L. They share many of the same applications.

316L is the ultra-low carbon variant of 316 stainless. It is purposed in chemical processing equipment, furnace pans, and marine tubing. Its superior corrosion resistance makes it an outstanding choice for heat exchangers, jet engine parts, evaporators, textile processing equipment, and tubing exposed to marine environments. It is an austenitic steel which will become slightly magnetic after significant cold working. The reason for this grades superior corrosion resistance is the addition of molybdenum.

409 grade stainless steel shows excellent corrosion resistance making it useful in applications like automotive and truck exhaust systems, heat exchangers, agricultural spreaders, fuel filters, gas turbine exhaust silencers, and other applications where severe forming requirements, toughness, and improved weldability are needed. Improved weldability is one of the main benefits of this stainless steel grade.

430 is a non-hardenable ferritic stainless steel. It is used in automotive trim and molding, dishwashers, range hoods, gutters, and flatware. It can also be purposed in oil refinery equipment, restaurant equipment, and roofing and siding. This grade is less amenable to welding.

439 is a ferritic stainless that improves on the corrosion resistance of 409 by resisting stress corrosion cracking and intergranular corrosion. It shows good weldability, high thermal conductivity, and low thermal expansion. You’ll see it in heat exchanger tubing, kitchen equipment, household appliances, and even architectural structures since this material can be easily formed into complex shapes.

441 stainless steel provides good high-temperature strength and offers good corrosion resistance in exhaust gas environments. You’ll find this grade steel in appliances, food and kitchen equipment, heat exchangers, and some architectural structures.
