The strict quality control of S690QL material properties processing

Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.

The S690QL material properties weathering steel plates are our main products, which are also called weather resistant steel plates, corten steel plates, atmosphere corrosion resistant steel plate, anti-corrosion plates, etc. The main recognized standards for weathering steel plates are ASTM CORTEN, ASTM A588/A588M, ASME SA588/SA588M, EN 10025-5, EN 10155, TBT 1979, GBT 4171, JIS G 3114, JIS G3125, ASTM A242/A242M, etc. Our typical weathering steel grades are Corten A, A588 grade B, S355J2WP, S355J0WP, 09CuPCrNi-A, 05CuPCrNi, Q355NH, SPA-H, A242 type 1, etc.

The preparation of S690QL material properties galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for S690QL material properties centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

ASTM a588 is a high strength low alloy HSLA steel (high strength, low alloy) containing a small amount of alloying elements copper, chromium and AMP. Nickel. These alloying elements effectively improve the properties of a588 and expand its application range. Firstly, the alloy composition increases the S690QL material properties yield point strength to 50 Ksi and the tensile strength to 70 Ksi. Secondly, a588 S690QL material properties has high copper content, atmospheric corrosion resistance and long working time. Because of its excellent comprehensive performance, a588 angle steel is widely used in bridge, building and other structural fields.

We have efficient and quick logistic team service. We promise that after the customer places the order, the spot products will be shipped, processed, and cut on the same day. The steel S690QL material properties products will be shipped in 2-5 days according to the characteristics of the product. The company has always been adhering to the service concept of "integrity, pragmatism, enthusiasm" and dedicated to providing our customers with high-quality steel products and after-sales service.

our company is a professional ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel exporter and a steel Stockist in china. We keep more than S690QL material properties 1000 tons ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel in stock every month.
