Reputable for producing and supplying stainless steel 347H stud bolts, Harshita Stainless is situated in Delhi, India, and provides high-performance fastening solutions for corrosive and high-temperature industrial applications. These stud bolts are perfect for critical environments like pressure vessels, boilers, and heat exchangers because of their exceptional durability and thermal stability. Precision threading, dimensional accuracy, and conformity to global standards for strength and corrosion resistance are all guaranteed by Harshita Stainless. Serving important industries like oil and gas, petrochemicals, power generation, and marine in both domestic and international markets, the company is dedicated to quality, on-time delivery, and customer satisfaction.
With iron serving as the base, stainless steel 347H Stud Bolts are made of chromium (17–20%), nickel (9–13%), carbon (0.04–0.10%), and niobium (columbium) for stabilisation. Excellent resistance to high-temperature oxidation and intergranular corrosion is provided by this composition. Mechanically, they offer elongation of at least 35%, yield strength of about 205 MPa, and tensile strength of about 515 MPa. With improved creep and stress rupture characteristics, 347H, a high-carbon version of 347, is appropriate for continuous use in environments with temperatures above 538°C.
