Product Description

304 316L stainless steel round pipe seamless or welded surface mill or bright finish




Stainless Steel Grade 304 is the standard 18/8 (18% chrome, 8% nickel) austenitic stainless steel. It is a non-magnetic alloy in the annealed condition but becomes magnetic as it is cold worked. It is the most commonly used of all stainless grades. TP304 can be easily welded and is the choice for many deep drawn, spun or formed parts due to its high ductility.

Stainless steel pipe is a kind of economic cross section steel, is an important product of iron and steel industry, which can be widely used in decorative and industrial life, many people on the market for making stair handrail, protective Windows, railings, furniture, etc., common are two kinds of material for 201 and 304.
Stainless steel pipes are widely used in petroleum, chemical industry, medical, food, light industry, mechanical instruments and other industrial conveying pipes and mechanical structural parts.
According to use can be divided into oil well pipe (casing, tubing and drill pipe, etc.), line pipe, boiler pipe, mechanical structure, hydraulic prop, cylinder pipe, geological, chemical pipe (high pressure chemical fertilizer pipe, oil cracking pipe) and tube for ships, etc.
In addition, it is also widely used in the manufacture of mechanical parts and engineering structures in the light of bending and torsional strength and light weight.
