Alloy Steel Gr 2H bolts are robust fasteners crafted from medium carbon alloy steel, specifically designed to handle high-pressure and high-temperature situations. These bolts often undergo a quenching and tempering process to boost their mechanical properties and durability when put under stress. The designation Gr 2H refers to a particular grade outlined in ASTM A194, which is typically utilized in high-pressure piping systems, valves, and flanges across industries like oil & gas, petrochemicals, and power generation. Engineered to meet strict specifications, these bolts ensure dependable performance in tough environments where strength, hardness, and resistance to mechanical stress are essential.
Made primarily from medium carbon steel, Alloy Steel Gr 2H bolts also include alloying elements like manganese, chromium, and molybdenum to enhance their strength and hardness. Their chemical makeup generally consists of carbon (0.40–0.50%), manganese (0.60–0.90%), phosphorus (max 0.035%), and sulfur (max 0.040%). After undergoing heat treatment, these bolts showcase impressive mechanical properties, boasting a minimum tensile strength of 150 ksi (1034 MPa), yield strength of 105 ksi (724 MPa), and high hardness levels typically ranging from 24 to 35 HRC. These features make them perfect for critical joints that face vibration, thermal cycling, or heavy loads.
