The 200 series is a class of austenitic and highly corrosion-resistant stainless steels that are characterized by having low nickel content. They’re also referred to as chrome-manganese (CrMn) stainless steel.
Austenitic steels include both the 200 and 300 series. They’re defined by their face-centered cubic structure. The crystal structure has one atom at each corner of the cube, and one in the middle of each face. This is different from ferritic steels, which are characterized by a body-centered cubic structure.
Although it’s corrosion-resistant, the 200 series has a lesser ability than the 300 series to protect against pitting corrosion.

Our 300 series of stainless steel is austenitic, with chromium levels ranging between 18–30% and nickel levels of 6% to 20%. We offer the following grades:

Due to its sulfur and phosphorus content, 303 stainless steel is highly machinable. It is typically used in the aerospace industry for fittings, gears, bolts, and nuts.

304 is the most commonly used austenitic stainless steel. 304L is a variation that has a lower carbon content. 304 finds use in a variety of industries, including automotive, food and beverage, nuclear, and shipping, while 304L is generally used in welding applications.

Compared to 304, 316 is less commonly used. The alloy contains more molybdenum and nickel and is available in a low carbon variation—316L. Its composition allows for higher corrosion resistance, especially to chlorides such as salt and sea water. 316 is suitable for use in nuclear plants and marine environments, while 316L often finds application in the pharmaceutical and chemical industries.

Both 321 and 321H contain titanium. However, 321H has a higher carbon content for greater temperature resistance. Both alloys are frequently used in chemical processing and oil and gas refineries.

347 and 347H contain a higher concentration of niobium and tantalum, making them suitable for welding applications. Both materials can often be found in airplane and automobile components and chemical storage tanks.

Our 400 series of stainless steel is martensitic, with chromium level ranging between 11–17%. We distribute the following grades:

410 is durable and highly resistant to wear but is more susceptible to chemical corrosion and oxidation. The material is often used in automotive parts, medical products, nozzles, pipelines, and valves.

416 contains sulfur, which allows for greater machinability. This quality makes it suitable for use in a variety of products, including valves, pumps, studs, gears, and washing machine components.

Due to its high carbon content, 440C is exceptionally hard and wear resistant; however, it is only moderately corrosion resistant. This material is useful for knives, surgical implements, nozzles, bearings, and other items that require that the material retain its shape under pressure.

Precipitation hardened stainless steels are prized for their excellent strength-to-weight ratio. Additionally, they are able to be heat hardened like martensitic stainless steel and offer corrosion resistance similar to austenitic stainless steel.

13-8 is a low carbon stainless steel with high tensile strength and corrosion resistance. It is frequently found in airplane components and nuclear equipment.

15-5 has exceptional corrosion resistance and durability. It is often used in the aerospace, chemical, food processing, and general metalworking industries.

17-4PH stainless steel contains higher quantities of chromium and copper. It is exceptionally strong and corrosion resistant. Its uses include offshore oil and gas and nuclear waste processing applications. It can also be found in airplane and automotive components.
17-4 stainless steel is similar to 17-4PH, but only undergoes a single heat treatment process during its manufacture. As such, it is softer but is generally used in the same applications.

Inconel® 718 is a precipitation-hardening nickel-chromium alloy containing significant amounts of iron, columbium, and molybdenum, along with lesser amounts of aluminum and titanium. 718 materials maintain high strength and good ductility up to 1300°F (704°C). This alloy has relatively good weldability, formability, and excellent cryogenic properties compared to other precipitation hardening nickel alloys. The sluggish precipitation hardening response of this alloy allows it to be readily welded without hardening or cracking. Inconel® Alloy 718 is non-magnetic. It maintains good corrosion resistance and oxidation resistance and is used for parts requiring high resistance to creep and stress rupture up to 1300°F (704°C) and oxidation resistance up to 1800°F (982°C).
