Stainless Steel 321H Fasteners description:
These fasteners are developed for use in elevated temperature where corrosion resistance application required. It has higher oxidation resistance up to 2010 deg F temp even in the intermediate temperatures. It has higher chromium and moderate nickel content that increase its resistance to sulfidation. These fasteners can also be used in moderate carburizing environments.
Because of the nickel content, it can be used in the harsh carburizing environments of thermal processing equipment. SS 321H fasteners can be used in concentric oxidizing, nitriding, thermal cycling, cementing applications. In this range of temp its maximum service in reduces. These fasteners are most beneficial in cryogenic applications with down magnetic properties. It is toughness down up to -450 deg F.
Stainless steel is subjected to sigma phase precipitation in temperature between 1202 deg F to 1742 deg F.
When it is exposed in the solution annealing process a higher degree of toughness is restored. It is also available in the lower amount of carbon. 321 H is the higher carbon version designed for improving the creep resistance. For instance, carbon composition can attain the needs of both higher and lower carbon version. Thus, these fasteners are easily weldable with all standard welding operations. However, it is readily processed from standard shop fabrication operations.
Stainless Steel 1.4878 Fasteners are developed for use in wet corrosive environments. 321H alloy has a detrimental effect on wet corrosion resistance. These fasteners are prone to intergranular corrosion attacks even after the long term exposure at elevated temperatures. The high amount of chromium content makes it more resistive than heat resistant alloys.

Excellence of Piyush steel:
Here our motto is to provide high-quality products more than doing business. We ensure only the finest qualified materials are used for the manufacturing of products. Our team of professional regulate a vigil on the quality of products. Each single piece is attached with test certificates and credentials. Thus, makes us able continually improving the quality of products. The main reports are raw material test report, specification guide, mill test report, fumigation certificates, quality assurance plan, heat treatment charts, national board approval lab (NBAL) test report, and more.
We practice stringent quality control measures for ensuring the products manufactured by us are made under global standards. Also, these tests assure the reliability and functionality of fasteners when these are exposed in the demanding application. It is processed from primary and secondary tests procedures.

Primary tests-
• Micro test
• Chemical analysis
• Macro test
• Positive material test
• Pitting corrosion test
• IGC test
• Radiographic test
• Ultrasonic test

Secondary test-
• Hardness test
• Mechanical test
