Correct welding method for S460QL equivalent grade

Fake and inferior steel plates are easy to scratch because of the simple equipment of the manufacturers of fake and inferior materials, which are easy to produce burrs and scratch the surface of the steel plate. Deep scratches reduce the strength of the S460QL equivalent grade, steel plate. The surface of the fake and inferior material is prone to cracks, because its billet is adobe, which has many pores. The adobe is subjected to thermal stress during the cooling process, and cracks are generated, and there will be cracks after rolling.

S460QL equivalent grade and so on steel structure engineering steel has good plasticity, which can make the structure have obvious deformation before being destroyed, so as to avoid brittle failure of structure. The good plasticity of steel can adjust the local peak stress to redistribute the stress, and improve the ductility of components, so as to improve the seismic capacity of the structure. The impact toughness of S460QL equivalent grade and so on steel structure engineering steel is good, which can improve the ability of resisting dynamic load and avoid the occurrence of cracks and brittle fracture.

We cooperated with the Peruvian government for many years. And supply them large diameter steel pipes and pipe fittings to support their Hydropower Station Projects. We do 100% UT, RT, Hydraulic test and so on tests for the S460QL equivalent grade steel pipes. And do PT, MT and so on tests for the pipe fittings.
We published "Welding Procedure Qualification report" after production. And our mill will keep the test record in the documentary department for 5 years. If meet any problems in following application, we can check the test record easily and assist to solve problems at the first time.

At the same time, the company operates a variety of products of related iron and S460QL equivalent grade steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained S460QL equivalent grade ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.
