API 5L X42 PSL2 grade steel,In terms of service, our service is a "one-stop" way of working. We have our own processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as cutting, welding, drilling, galvanizing, etc., at the lowest cost.

S355J2 is a low-alloy high-strength steel, which can be treated to meet the requirements of Z-15, Z-25, Z-35 and level I, level II and level III flaw detection.
The extension grades of S355J2 are S355J2, S355J2-Z35 and S355J2 + N-Z35, . On the basis of S355J2, S355J2-Z35 increases the requirement of S355J2 steel plate thickness direction performance, namely Z-direction performance. S355J2 + N-Z35 is a heat treatment process which increases Z-direction properties and normalizing rolling (or normalizing).

X56 steel plate is a kind of steel mainly used for large-diameter pipelines. API X56 steel plate is used to manufacture buried pipelines for natural gas transmission. Due to the corrosion of soil, serious degradation will occur. The corrosion type of X56 steel plate that can be produced is usually general corrosion and pitting. we are API 5L X56 steel suppliers ,we also can supply API 5L X52,API 5L X60,API 5L X65,API 5L X70,API 5L X80,please contact us if you need.

API 5L X42 PSL2 grade steel,In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate size.
