321 Stainless Steel Square Tube

Our company is based in Tianjin, China. We are SGS certificated. 

Stainless Steel Pipe ASTM EN Standard
 
Model No.: ASTM304, 304L, 316, 316L, 321, 317L, 309S, 310S, 2205, 2507, 904L 254SMO, 1.4529, 316Ti, 253MA, 654SMO, 201, 202, etc.
 
Stainless steel is a steel alloy with a minimum of 10.5% chromium content, as well as certain Ni, Mo, Mn, Cu, N contents etc.
Stainless steel does not readily corrode, rust or stain with water. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and corrosion resistance are required.
Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion and blocks corrosion from spreading into the metal.
 
Physical and chemical properties:
High oxidation resistance in air at ambient temperature;
Highly resistant to attack from acids, bases, organics;
High resistance to stress corrosion cracking;
High resistance to general corrosion, pitting corrosion, crevice corrosion, erosion corrosion and corrosion fatigue;
High mechanical strength.
 
Specifications:
Seamless pipe: Φ32*3.5mm~Φ630*9mm
Straight welded pipe: DN15mm~150mm
Spiral welded pipe: DN150mm~2600mm
Square pipe: 7*7mm~150*150mm, thickness: 0.4mm~8mm
Rectangle pipe: 10*20mm~30*90mm, thickness: 0.4mm~10mm
Any spec as per customer require
 
Process method:
Seamless pipe: hot rolled, cold drawing
Welded pipe: straight welding, spiral welding, ERW, LSAW, SSAW
 
Applications:
Steel stainless steel is widely used for the working environment of corrosion, high temperature, high pressure, abrasion and wear, creep deformation etc., in the industries of oil and gas, petrochemical, electric heating, power plant, industrial plant, metallurgy, metal working, coal, mining, machinery, shipbuilding, construction, engineering, automotive components, industrial boiler, sewage system, chemical fertilizer, paper and pulp, offshore platform, sea water system, food processing, medical, pharmaceuticals etc.

Packing:
standard export packing, seaworthy packing, bundles, plastic bag, woven bag, wooden cases, plywood case, iron case, or as per customer require.

We have bulit strategetic partnership with TISCO, POSCO, BAOSTEEL, LISCO  several years. Customers shouldn't have concern with our products, product could endure time.
