Welcome to BBN High Strength Steels Factory
In terms of service, our service is a "one-stop" way of working. We have our own S690Q chemical composition 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 S690Q chemical composition cutting, welding, drilling, galvanizing, etc., at the lowest cost.
Wear resistant steel plate S690Q chemical composition is an important material for industrial application. The traditional wear resistant steel is the high manganese steel which hardens under the impact load. The premise of its function must be subjected to enough impact load. With the development of wear resistant steel technology, NM series steel plate breaks through the limitation of traditional high manganese steel and realizes the application space of wear-resistant steel. The main S690Q chemical composition grades of NM series wear resistant steel plates are NM360, NM400, NM450, NM500, NM550, NM600.
S690Q chemical composition and so on steel structure engineering steel has good plasticity, which can make the structure have obvious deformation before being destroyed, so as to avoid brittle failure of structure. The good plasticity of steel can adjust the local peak stress to redistribute the stress, and improve the ductility of components, so as to improve the seismic capacity of the structure. The impact toughness of S690Q chemical composition and so on steel structure engineering steel is good, which can improve the ability of resisting dynamic load and avoid the occurrence of cracks and brittle fracture.
EN10149 S355NC steel plate/sheet,EN10149 S355NC steel plate/sheet, under EN standard, we can regard S355NC steel plate/sheet as S690Q chemical composition high strength steels for cold-forming, normalised steel. EN10149 S355NC is mainly used as high strength steels for cold-forming,normalised steels.The EN10149 S355NC steel grade offers excellent bending,flanging cold
S690Q chemical composition, ASTM A131 shipbuilding steel has different grade levels. The ordinary strength shipbuilding steel grades are grade A/B/D/E. Their min. yield strength is 235 Mpa, and tensile strength is 400-520 Mpa. The higher strength shipbuilding steel grades are grade AH32/DH32/EH32/FH32, AH36/DH36/EH36/FH36 AH40/DH40/EH40/FH40. The min. yield strength of AH32/DH32/EH32/FH32 steel is 315 Mpa, and tensile strength is 440-590 Mpa. The min. yield strength of AH36/DH36/EH36/FH36 steel is 355 Mpa, and tensile strength is 490-620 Mpa. The min. yield strength of AH40/DH40/EH40/FH40 steel is 390 Mpa, and tensile strength is 510-650 Mpa.
We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
