Low-alloy high-strength steel refers to low-alloy engineering structural steel with a small amount of alloying elements added to low-carbon steel so that the yield strength in the rolled or normalized state exceeds 275 MPa. Our company can provide low alloy high strength steel plate including: S355, S355JR, S355JO, S355J2, S355N, S355NL, S460Q, S460QL, S500Q, S500QL, etc. European standard low alloy high strength steel plate. In this article I will introduce S500QL high strength low alloy steel plate in detail.
S500QL is the European standard high strength structural steel, usually called high strength plate in China, its composition and performance is equivalent to the national standard Q500D high strength plate, because of its excellent practical performance and is widely used in construction machinery, mining machinery manufacturing use.

S500QL steel plates are delivered in the quenching and tempering heat treatment state of quenching + tempering. The purchaser can add flaw detection standard requirements, flaw detection level requirements, alloy element composition control requirements, thickness direction performance requirements (Z-direction performance, such as S500QLZ35), etc. according to the needs. However, It is necessary to communicate with the manufacturer in advance and sign a written agreement when making inquiries or ordering rolling.
