As this grade is made of pure stainless steel it possesses great affinity to stand against corrosion due to its chromium content. This grade is slightly ferritic and austenitic. It comes in both tempered and quenched state. The pipes we offer has good machining capability and tolerance limit so as to fit in different types of applications. These have good pitting and crevice cracking resistance even at high temperatures. The moderate quenching with water makes them tough enough to stand in reducing environment.

Spinning the finest raw grade we are able to provide only durable products to our customers. The surface finish process makes the design of pipes sturdier and uniform. Additionally, these are coated with the extra protection of bright black polish that prevents from oxidation too.

Quality measures:
Quality is a great aspect to become a reputable dealer as we believe. Therefore each step of production is surrounded by the quality inspection team. They conduct the following tests- hardness test, tensile test, positive material test, micro and macro test, chemical test/ spectro analysis and intergranular corrosion test. These tests check the reliability of the product. We especially take care that none of SS 321 / 321H Seamless Pipes get damaged while transit so we use wooden boxes, crates, cases, and pallets.
