Luke Steel is a trustworthy Alloy Steel Gr 2H Bolts supplier in Houston, USA. These heavy hex bolts are suited for applications in high-pressure as well as high-temperature conditions. Gr 2H bolts are heat-treated carbon steel fasteners employed mainly in flanged connections and pressure vessel assembling. They meet ASTM A194 standards and are usually coated or galvanized for increased corrosion protection. As a company known for precision manufacturing and performance, Luke Steel‘s Gr 2H bolts are highly relied upon across the oil & gas, power generation, and petrochemicals industries for their strength and reliable sealing performance.
Gr 2H bolts are manufactured using medium-carbon alloy steel with a general composition of 0.40% carbon, manganese, and minute quantities of trace elements. Gr 2H bolts are hardened by quenching and tempering to produce minimum tensile properties of 860 MPa and yield properties of 690 MPa. Due to their high hardness and toughness, they can be used for high-pressure bolting. The heat treatment increases grain refinement and mechanical strength with resistance to creep and stress relaxation. The bolts are stable in high temperatures and aggressive environments, making them well-suited to pressure vessels, flange connections, and structural frames needing secure fastening.
