Luke Steel produces and exports Alloy Steel Gr 2HM Bolts from Houston, Houstan, with expertise in high-temperature, hydrogen-resistant bolting solutions. The bolts are specifically intended for sour gas and hydrogen sulfide (H₂S) environments and are suitable for offshore and petrochemical installations. Gr 2HM bolts meet ASTM A194 specifications and are completely heat-treated for improving mechanical properties. With dimensional precision and accuracy threading, Luke Steel guarantees each bolt of leak-proof performance in high operating conditions. Our Gr 2HM bolts offer strength, corrosion resistance, and extended service life in severe chemical and pressure conditions.
Gr 2HM Bolts are alloy steel fasteners with 0.40% carbon, manganese, and chromium-molybdenum content to provide additional strength and corrosion resistance. They are subjected to tempering and quenching to obtain tensile strength of 860 MPa and minimum yield strength of 690 MPa. Thoroughly engineered to meet sour service requirements, they possess superior resistance to hydrogen embrittlement and sulfide stress cracking. The bolts maintain their structural strength under high-pressure and elevated temperature operation. Gr 2HM bolts are used in critical flange connections and provide long-term reliability under aggressive fluid environments and pressure cycling.
