Q420 angle steel is a kind of low alloy high strength steel. Q represents the strength of steel, 460 representatives of 460 MPa,M is 6 to the power of 10, Pascal Palmer is a unit of pressure. Q420 angle steel is the steel stress strength up to 460 MPa willoccur plastic deformation, namely when external leak, steel can only maintain the force of the shape and cannot reply prototype, this strength than ordinary steel large.
Q420 angle steel based on guaranteeing the low carbon equivalent, an appropriate increase in the content of microalloy elements. Good welding performance requirements of steel low carbon equivalent, and micro alloy elementsincrease to the increase in the strength of steel at the same time, also will increase the equivalent carbon steel. Butthe carbon equivalent fortunately increased very little, so will not affect the weldability of steel.
