Austenitic Seamless pipes
Austenitic stainless steels account for more than 70% of stainless steel production, with type 304 being the most common grade of stainless steel used. The basic composition of austenitic steels is 18% chromium and 8% nickel. However, type 316 contains 16% to 18% chromium and 11% to 14% nickel which make it exceptional for applications in corrosive environments. The nickel content is higher in austenitic than ferritic and martensitic stainless steels. The steel is non-magnetic, is hardened significantly by cold-working and is known for its high corrosion resistance, formability, weldability, and other fine mechanical properties. The austenitic grades are found in the 200 series and 300 series, and are widely used for cookware, food and beverage equipment, processing equipment, and also in the automotive industry, chemical processing,, and the pulp and paper industry.

Ferritic Seamless Pipes & Tubes
Classified in the 400 series grade, ferritic stainless steels account for approximately 20% of the stainless steel market. They consist of a lower carbon with varying chromium content between 10.5% and 18% and, like martensitic stainless steel, it contains no nickel. Ferritic steels are magnetic, have good ductility, and formability, and, like austenitic stainless steels, are not heat-treatable. They are highly resistant to stress corrosion cracking, offer very good tensile-property stability and have better thermal fatigue resistance, lower thermal expansion, and higher thermal conductivity than austenitic grades. The most common ferritic grade is type 430, known for its high corrosion resistance to nitric acid, sulfur gases, and many organic and food acids. Other grades are type 405, 409, 434, 436, 442, and 446. In general, ferritic steels are used in elevated-temperature applications such as exhaust systems for vehicles. Other applications for ferritic stainless steel include petrochemical components, automotive trim, heat exchangers, furnaces, appliances, and food equipment to name a few.
