JIS SM520B plates for bulletproof walls

Automobile steel sheet is mainly used to manufacture automobile girders (longitudinal and cross girders), frame and other structural parts. The automobile girder should not only bear heavy static load, but also bear certain impact, vibration, etc., so the steel sheet JIS SM520B plates is required to have certain strength and fatigue resistance, as well as better stamping performance and cold bending performance to meet the requirements of cold stamping processing.

Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and JIS SM520B plates resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, JIS SM520B plates new materials, and promotes the competition of enterprises Struggle.

Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This JIS SM520B plates method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.

30CrMnSiA steel delivery status: JIS SM520B plates, 30CrMnSiA steel shall be delivered in the state of heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment, and the delivery status shall be indicated in the contract. 30CrMnSiA steel has high strength, but it belongs to medium carbon quenched and tempered steel, with large hardenability, so its weldability is very poor. After quenching and tempering, 30CrMnSiA steel has high strength, enough toughness and good hardenability. And can be used as grinding wheel shaft, gear and sprocket.
