High strength StE315 grade structural steel size

As a pipeline of oil and natural gas, spiral pipe has its own characteristics: 1. The amount of use is large, because the specifications of StE315 grade structural steel, spiral pipe used in a project are often diversified. During the forming process of the spiral pipe, the steel plate deforms evenly, the residual stress is small, and the surface does not occure scratches. 2. The spiral pipe is used in a complex environment, and the quality must be guaranteed, otherwise it will delay the follow-up project progress.

4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. StE315 grade structural steel, 4140 steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering treatment, and good low temperature impact toughness. 4140 steel is suitable for manufacturing large and medium plastic mould with certain strength and toughness.

Medium and thick steel plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on. However, each project has different requirements for plate size. How to cut StE315 grade structural steel, medium and thick steel plates? There are many ways, for example, flame cutting, laser cutting, wire cutting, plasma cutting, ultra-high pressure water cutting and so on.

We have a professional production team and high-quality production equipment, and we also have a great StE315 grade structural steel advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the StE315 grade structural steel production of high-quality steel plates, steel pipes and other products that meet customer requirements.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
