Ed Stainless’s Stainless Steel 442 stud bolts are mainly composed of an iron alloy with 17-19% chromium and 0.3-0.5% nickel content, providing improved corrosion resistance along with strength. The duplex stainless steel grade is highly resistant to oxidation and has stable behavior at high temperatures. Mechanically, the stud bolts have high tensile strength, generally in the vicinity of 650 MPa, and are good in terms of toughness and hardness. The combination of nickel and chromium provides resistance to crevice and pitting corrosion and makes these bolts suitable for harsh environments while retaining structural integrity during mechanical stress.
