SUS 321 347 316 3 4 Stainless Steel Pipe Round

321 stainless steel is a derivative of 304 stainless steel. There is not much difference in corrosion resistance. However, under heat-resistant conditions of 500-600 degrees Celsius, 321 stainless steel is mostly used because 321 stainless steel has TI as a stabilizing element. , which effectively controls the formation of chromium carbide, and is also a heat-strength steel, giving it better intergranular corrosion resistance and high-temperature strength, so it can be used to manufacture wear-resistant acid containers and linings of wear-resistant equipment. conveyor pipeline.
316 stainless steel is an austenitic stainless steel. The addition of Mo element greatly improves the corrosion resistance and high temperature strength. It can withstand high temperatures of 1200-1300 degrees and can be used under harsh conditions. The tensile strength (Mpa) of 316 stainless steel is 520MIN, the yield strength (Mpa) is 205MIN, and the elongation (%) is 30MIN.

Features

• High strength
• Scaling resistance and phase stability
• Excellent forming and welding characteristics
• Resistant to potable water with up to 200mg/L chlorides at normal temperature.

Applications

Ideal uses for 321 Stainless Steel include expansion joints, aircraft parts, furnace parts, heat exchangers, mineral processing screens, welding by all standard methods, with or without filler metal.
