The steel coil S355J0W complete specification weldability from BBN

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for steel coil S355J0W complete specification various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several steel coil S355J0W complete specification after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

steel coil S355J0W complete specification, low alloy high strength steel has good weldability. Welding is the most common method to construct engineering structure, so the steel used in engineering structure requires good welding performance. Low alloy high strength steel has low carbon content, low alloy element content and good plasticity, so it is not easy to produce quenching structure and crack in the weld area, and the addition of Ti, Nb, V can also inhibit the grain growth in the weld area. Therefore, most of the low alloy high strength steels have excellent welding performance and no heat treatment is required after welding.

Laser cutting steel coil S355J0W complete specification has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the steel coil S355J0W complete specification cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.

In April 2018, our Philiphine customer purchased 1008 Tons API5 L Gr.B ERW&Q345B SMLS pipe steel coil S355J0W complete specification 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.
