S690QL steel vs european alloy steels

S420M and S420ML are hot-rolled flat weldable fine-grained structural steel with a thickness less than 120mm. S690QL steel, S420 steel is a non-alloy structural steel. The S420ML steel is composed of the following parts: S (structural steel); 420: the yield strength value of structural steel with a thickness less than 16mm: not less than 420; M represents his delivery status, that is, hot mechanical rolling; L: The impact when the temperature is not lower than -50 degrees is marked with a capital letter L.

EN10083-3 42CrMo4 steel plate delivery status: Heat treatment (normalizing, annealing or high temperature tempering) or non-heat treatment delivery status should be specified in the contract. EN10083-3 42CrMo4 steel plate equivalent materials: JIS SCM440, AISI 4140, GB 42CrMo, S690QL steel etc. EN10083-3 42CrMo4 steel plate has high intensity, high hardenability, high fatigue strength and good low-temperature impact toughness.

The related factors of S690QL steel steel plate cutting are mainly steel plate material, steel plate specific use and steel plate cutting requirements, so it can be said that there are many related factors. Different processing methods, such as finish machining and rough machining, choose different S690QL steel steel plate cutting methods. Wire cutting or plasma cutting is used for finishing and flame cutting is used for rough machining. Therefore, it can be concluded that the steel plate cutting methods selected under different processing methods are different.

BBN company is an industry leading steel service center that supplies a full line of hot rolled steel plate in a variety of sizes, grades and finishes. Hot rolled steel is an economical option that offers reliable performance and versatility. In the S690QL steel hot rolled process, high temperature is used to heat the steel above its recrystallization point. In this state it becomes more malleable, allowing it to be easily formed into a variety of shapes. If you are interested in A36 hot rolled plates price, welcome to come and visit us.
