Navgraha Steel & Engg Company provide Stainless steel 253 MA Fasteners made from the best quality raw materials. So, We provide the best quality of the product. It is a grade that using combine outstanding assistance features at heat raised with the efficiency of fabrication. The combination of high silicon, nitrogen and cerium substances provides us with the substance like iron with good oxide stability. The grade 253 MA offers excellent performance. In addition, the fasteners is low in nickel. So, it helps us to reduce sulfur atmosphere. Also, it gives a high raised temperature and excellent resistance to sigma point precipitation. The product contains austenitic formation, which provides standard toughness, even down to cryogenic temperature. For example, in the environment, it performs as isothermal and cyclic oxidation. Also, it has a carburising atmosphere that contains various combustion and combustion gases.

Stainless steel 253 ma Fasteners is an austenitic heat resistant alloy with high strength and outstanding oxidation resistance. It provides an excellent combination of creep strength with outstanding resistance to oxidation, sulfidation and erosion at high temperatures. Also, it contains good resistance because of particularly cyclic oxidation.
These alloys have less percent nickel because of its lean chemistry. Because of tight control micro-alloy, the fasteners obtain its heat resistant properties. The combination of elements has cerium and silicon results are like in superior oxidation resistance. The product contains creep rupture strength because of its components such as nitrogen, carbon, and cerium.
