What is the scope of appearance inspection of S890QL equivalent

In terms of service, our service is a "one-stop" way of working. We have our own S890QL equivalent processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as S890QL equivalent cutting, welding, drilling, galvanizing, etc., at the lowest cost.

Vanadium is a weak deoxidizer. Adding vanadium into S890QL equivalent steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

Q960 belongs to high strength structural steel plate, which is delivered in the state of quenching and tempering (tempering + normalizing). The yield strength of Q690 steel is more than 960Mpa, the general thickness is not more than 50mm, and most of the thickness is less than 30mm. Therefore, S890QL equivalent, Q690 steel is widely used in the manufacture of more than 100t tramcar floor, pumping machinery, excavator, truck crane, crawler crane, coal mine hydraulic support, etc.

BBN steel company establishes a sound safety management system from the following aspects: First, it is necessary to improve the safety management system. Iron and steel enterprises should improve the existing safety management system in accordance with safety management policies, laws and regulations, and formulate specific implementation plans, determine clear operating specifications, inspection requirements, evaluation standards, etc., and also add special inspection posts or department, formulate a strict inspection system to ensure that various rules and regulations and implementation plans can be effectively implemented to ensure strict management and control of security risks.
