Do you want any logistics service, then call us: +86-371-86151827
As an experienced world class steel materials supplier and exporter, logistics and fast delivery is a crucial step to us. Our logistics department and shipping department take the responsiblity to allocate and transport steel materials from our mill and warehouse to customer port or designated destination. The cooperation of the two departemts are excellent and that powerfully support our fast delivery, and strive for shorter time for customers to receive steel materials.
Weathering steel is characterized in that the alloy composition and weight percentage content. The chemical composition C≤0.12, Si: 0.25 ～ 0.75, Mn: 0.20 ～ 0.50, P: 0.07 ～ 0.15, S≤0.03, Cu: 0.25 ～ 0.55 , Cr: 0.30 ～ 1.25, Ni≤0.65, and the rest are Fe and trace impurities. Weathering steel sheet a242 type 1 weather resistant steel plate is mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time.
The preparation of a242 type 1 weather resistant steel plate 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 a242 type 1 weather resistant steel plate centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
In April 2018, our Philiphine customer purchased 1008 Tons API5 L Gr.B ERW&Q345B SMLS pipe a242 type 1 weather resistant steel plate for offshore oildfield resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.
