Harshita Stainless, a prominent manufacturer and supplier located in Delhi, India, specializes in high-performance Stainless Steel 330 Fasteners that are built to withstand extreme temperatures and highly corrosive environments. Known for their precision manufacturing, commitment to quality, and customer-focused service, Harshita Stainless provides robust fastening solutions that cater to the needs of demanding industrial applications. These fasteners are expertly designed to excel in conditions involving heat, oxidation, and thermal cycling. They serve a variety of industries, including heat treatment, chemical processing, and power generation, offering Stainless Steel 330 Fasteners in a range of sizes and specifications to meet both standard and custom application needs.
Stainless Steel 330 is a high-temperature, corrosion-resistant alloy made up of about 18–20% chromium, 34–37% nickel, 1–1.5% silicon, along with trace amounts of carbon, manganese, and iron. This alloy boasts exceptional resistance to oxidation and carburization, especially in high-temperature settings. SS 330 fasteners deliver a tensile strength of 550–690 MPa, a yield strength of around 205 MPa, an elongation of 30–45%, and a hardness rating of 85–95 HRB. These characteristics ensure mechanical stability and reliable performance in both thermal and corrosive environments, making it a top choice for high-heat industrial applications.

We are committed to customer satisfaction with our products. To achieve this we conduct thorough testing on our SS 330 Fasteners to guarantee both safety and purity. We also test hardness, PMI, mechanical properties as well as flare and micro/ macro examination. All these checks are made so that there may not be a problem with the product we have produced. Our products go for a third-party check on quality in accordance with both national and international standards before it hits the markets. Only then do we introduce Stainless Steel 330 Fasteners into the market after their release.
Stainless Steel 330 Fasteners find extensive use in heat treating equipment, industrial furnaces, thermal processing systems, and gas turbine components, where resistance to thermal cycling and oxidation is crucial. They are particularly well-suited for petrochemical refineries, cement plants, power stations, and waste incinerators, providing excellent structural reliability even at elevated temperatures. Additionally, they perform admirably in exhaust systems, burners, and reformer tubes, maintaining their integrity under continuous thermal stress. Furthermore, Stainless Steel 330 Fasteners are utilized in the chemical processing and metallurgical industries, where their resistance to scaling and carburization is essential.
