Stainless Steel Grades

As stainless steel suppliers, our products are frequently used for engineering and industrial applications. Their general properties include strength, corrosion resistance, and fabrication characteristics. Below is an overview of the types of stainless grades, stainless steel products, and as well as their properties and industry uses.

200 Series

• Type 201: This stainless steel is less resistant to corrosion than the 300 series but provides higher yield strength. Uses include cooking utensils, stainless steel coils, trailer structures, and kitchen equipment.

300 Series

• Type 301: This type features a high corrosion resistance as well as ductility and strength. Common uses include auto trims and springs.

• Type 302: This type has a high strength with a low weight, is resistant to oxidation, and is easy to fabricate. Common applications are stainless flatware, and cooking utensils.

• Type 304, 304L: This type is resistant to many organic and inorganic chemicals, as well as architectural rusting. Serves many applications, such as applications in food processing plants, and architectural industries.

• Type 305: This type is easy to clean and fabricate with a high strength to weight ratio and low work hardening. Ideal for free spinning and cold heading. Common uses include mechanical components and spring clips.

• Type 308: This type has a higher oxidation and corrosion resistance than type 305 and contains properties of heat resistance, ductility, and weldability. Applications include oven and furnace parts, pump parts and boiler baffles.

• Type 309: This type features a high temperature resistance, strength, and weldability. Common uses include tube supports, fire box sheets, as well as oven and furnace parts.

• Type 316, 316L: This type contains a higher nickel ratio than type 304, providing it with a higher corrosion resistance and strength. 316L is easily maintained and features good pitting resistance and creep strength. Common uses include conveyors and food processing equipment.

• Type 317: This type features high tensile strengths and a good resistance to pitting. Commonly used for chemical processing tanks, pharmaceutical vessels, and storage tanks.

• Type 317L: This type contains a high corrosion resistance, high creep and tensile strength. It is also resistance to rupturing from high stress, and is used for processing and storage tanks for corrosive elements.

• Type 321: This type has excellent resistance to extreme temperatures, and has high strength due to its stabilization by titanium. Common uses include cabin heaters, flash boilers, aircraft afterburners, and firewalls.

• Type 326: This type features high strength, cold workability, and good corrosion resistance. This type is commonly used for fasteners.

• Type 332: This type is highly corrosion resistant, and resists oxidation at high temperatures. It has superior creep stress rupture characteristics. Common uses include boiler/pressure vessels, nuclear vessels, and appliance heating elements.

• Type 334: This type is resistant to scaling, oxidation, and corrosion. Common uses include electric heating element sheathing, and automotive emissions control systems.

• Type 347: This type is stabilized by tantalum and columbium, which gives is a high strength and immunity to high temperatures. Common applications include exhaust manifolds, stack liners, flash boilers, and boiler casings.

• Type 404: This type contains great formability, durability, ductility, and deep drawing. Usual applications include deep draw parts, radiator and gas caps, heat exchangers, and automotive components.

• Type 405: This type has oxidation and corrosion resistance, good ductility, and is easily formed and machined. Common uses include vessel linings, refining equipment, and heat exchanger tubing.

• Type 409: This type features a low alloy content and is used for highly stressed parts requiring both strength and corrosion resistance. Common uses include fasteners, automotive exhausts, and structural support.

• Type 410: This type is corrosion, heat, oxidation, and scaling resistant. It is also easily welded and has high impact strength. Typical uses include turbine blades, kitchen utensils, fasteners, and valve parts.

• Type 420: This type is durable, with good corrosion resistance, and can be hardened to 500 BHN. Commonly used for surgical instruments, hospital equipment, valve parts, and dental equipment.

• Type 430: Containing a lower alloy ratio than type 304, this type has good thermal conductivity, ductility, formability, low work hardening, and is resistant to corrosion and oxidation. Commonly used in nitric acid and food service processing, heat exchangers, and kitchen trims.

• Type 434: This type features superior scaling resistance, formability, ductility, good deep drawing, and easy maintenance. Common applications include plant machinery and automotive trims.

• Type 436: This type is resistant to corrosion and scaling, with good deep drawing and a bright finish. This type is commonly used for stretch formed parts.

• Type 442: This type is resistant to scaling and corrosion. Common applications include heaters, fittings, stack dampers, and furnace parts.
