ASTM A36 Available in standard and heavy thicknesses, ASTM A36 steel plate is one of the most popular materials used in structural applications in the United States.
ASTM A572 The A572 is used in a variety of structural applications, and is available in five grades: 42, 50, 55, 60 and 65.
ASTM A588 Stocks and supplies ASTM A588 corrosion-resistant structural steel plate.
AR450/AR500 Abrasion Resistant Supplies large quantities of AR450/AR500 steel plate, which offers more surface hardness than AR400 without compromising formability.
ASTM A690 is a standard specification for high-strength low-alloy (HSLA) structural steel designed for marine environments. It covers phosphorus-chromium-nickel-copper steel H-piles and sheet piling of structural quality.
ASTM A106 is the standard specification for seamless carbon steel pipe designed for high-temperature service. It is widely used in power plants, refineries, and chemical facilities.
ASTM A234 is the standard specification for piping fittings of wrought carbon steel and alloy steel for moderate and high-temperature service. It covers seamless and welded-type fittings used in pressure piping systems.
ASTM A516 is a PVQ carbon steel plate intended primarily for service in welded pressure vessels at moderate or lower temperatures, where notch toughness is important.
AISI 4140 is a versatile chromium-molybdenum low-alloy steel renowned for its exceptional toughness, high fatigue strength, and excellent wear resistance. It is widely used across the oil, gas, and automotive industries.
AISI 6150 is a high-carbon chromium-vanadium alloy steel renowned for its outstanding resilience, high fatigue strength, and excellent wear resistance. It is primarily utilized in the manufacturing of heavy-duty springs and high-stress components.
ASTM A240 is the standard specification for chromium and chromium-nickel stainless steel plate, sheet, and strip used in pressure vessels and for general applications. It is the premier standard for industrial stainless steel.
ASTM A312 is the standard specification for seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipe. It is specifically engineered for high-temperature and general corrosive service.
