A36 steel is the most common type of steel used in construction, it is commonly addressed as mild steel in South East Asian Region. ASTM A36 strictly regulated by American Society for Testing and Materials (ASTM) special designation for carbon steel. Unlike higher-performance alloys, its properties allow the steel to be used in many applications. We supply ASTM A36 steel plate from WISCO, BAOSTEEL and other state-owned steel mill. 

Steel alloys have differing amounts of other materials, such as carbon, nickel, manganese, tungsten and molybdenum on top of major material-iron. The different compositions create different properties among alloys that affect the modulus of elasticity, measurement of stiffness and toughness etc. Modulus of elasticity is used to calculate when a piece of steel will deform too much to carry a load safely. Other properties of steel include yield strength-maximum stress before the steel deforms permanently, allowable bending stress- stress the steel can safely carry before contorting out of plane and ultimate limit-stress at which the steel will completely fail.

ASTM A36 significantly offers a yield strength of 36,000 psi and an allowable bending stress of 22,000 psi. The properties of ASTM A36 steel allows it to deform steadily as stress is increased beyond its yield strength in order to allow the buildings to stand long enough after the limits of a structure have been met in an emergency thus allowing the inhabitants to exit safely before collapse takes place. Other high-performance steels, such as bridge strand, are extremely strong but brittle, and there is minimum deformation before the bridge strand breaks violently.
