SM490B steel, A514 grade Q steel material is a kind of low carbon welded structural steel. With this low carbon equivalent, it can produce good cold forming properties. SM490B steel plate is usually supplied in hot rolling or controlled rolling delivery conditions. The SM490B is commonly used in the engineering and construction industries. It has high yield and tensile strength, and provides a variety of processing and testing options to make it highly available in your construction projects.

A514 grade Q steel material,,A514 grade Q steel material., 20CrMo alloy steel plate has high hardenability, no temper brittleness, good weldability, little tendency of cold cracking, good machinability and cold strain plasticity. 20CrMo alloy steel plate is generally used in the state of quenching and tempering or carburizing and quenching. 20CrMo alloy steel plate is used to manufacture high-pressure pipes, fasteners and carburized parts, such as gears and shafts, working in non corrosive medium and medium containing mixture of nitrogen and hydrogen under 250 ℃.

Try to use high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.A514 grade Q steel material

S355J2 steel plate yield strength Rp0.2≥265mpa, tensile strength RM: 450-680mpa, elongation a≥12%, impact energy Kv2≥27J, tensile area shrinkage Z≥35% in thickness direction. S355J2 steel plate has good internal quality, high density and stable performance.Meaning of S355J2-Z35: J2 requires negative 20 degree impact, and Z35 is the Z-direction performance of S355J2 steel plate.The meaning of S355J2 + N-Z35: J2 requires negative 20 degree impact, N means normalizing rolling rather than normalizing. Z35 is the Z-direction performance of S355J2 steel plate.A514 grade Q steel material

A514 grade Q steel material,Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
