Introduction Low Alloy Structural Steel (Lukens A242)
Low alloy structural steel is to point to in adding a small amount of ordinary carbon steel or trace alloy elements, and make the steel performance change, get more excellent steel than ordinary carbon steel performance, also has special features such as high temperature resistant, resistant to low temperature. Due to the amount of alloy element in this kind of steel to join, this kind of alloy steel belongs to low alloy steel.
Low alloy steel including weldability of high strength low alloy structural steel, low alloy weathering steel, steel with low alloy steel, railway with low alloy steel, low alloy steel for mine and he low alloy steel.
Application(Lukens A242)
They are used in cars, trucks, cranes, bridges, roller coasters and other structures that are designed to handle large amounts of stress or need a good strength-to-weight ratio. HSLA steel cross-sections and structures are usually 20 to 30% lighter than a carbon steel with the same strength.
