When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials S275M plates. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.

40CrMo alloy structural steel specification Grade: 40CrMoStandard: GB/T 3077-1988Mechanical properties:Tensile strength σb (MPa): ≥1080 (110)Yield strength σs (MPa): ≥930 (95)Elongation rate δ5 (%): ≥12Section shrinkage ψ (%): ≥45Impact energy Akv (J): ≥63Impact toughness value αkv (J / cm2): ≥78 (8)Hardness: ≤ 217HBSample size: Sample blank size is 25mm

We have a large number of S275M plates steel materials in stock, and provide deep processing services such as welding. In addition to simple welding parts, we can also weld H-beam, box column and other profiles. For such welded structure, our advantage is that there are high-quality and low-cost raw material steel plates, which can be cut into the S275M plates required size and welded into steel products with required shape and size, without being limited by the specifications of rolling production lines.

The chemical composition of Q345D seamless steel pipe is as follows: C ≤ 0.18, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S≤ 0.025, Nb ≤ 0.07, V ≤ 0.15, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.012, Mo ≤ 0.10, Al ≥ 0.015. S275M plates, Q345D seamless steel pipe has good comprehensive mechanical properties, low temperature impact toughness, corrosion resistance, cold stamping, machinability and weldability. Q345D seamless steel pipe is widely used in welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, etc..

Land transportation inquiry: (RMB fee) it is required to master the kilometers and towing price of major cities; packing price of each port area; customs clearance fee, commodity inspection fee, and animal and plant inspection fee standard. Key information to be clarified after accepting the consignation of the consignor (generally fax): shipping date, number of packages, box type, box quantity, gross weight and volume.

The company always adheres to the quality policy of "Quality First, Continuous Improvement, Customer Satisfaction" and the business philosophy of "Continuous Progress, Pursuing Excellence", as always, we look forward to cooperating with you to create a new situation for common development.Steel products S275M plates price concessions, rich industry experience, complete varieties.
