Why EN steel grade S275JR material quality is so important

The pipeline steel coil EN steel grade S275JR material and plates are our main products. And the most popular standard for pipeline steel is API 5L. We mainly supply API 5L grade B (L245), API 5L X42 (L290), API 5L X46 (L320), API 5L X52 (L360), API 5L X56 (L390), API 5L X60 (L415), API 5L X65 (L450), API 5L X70 (L485) pipeline steel coil and plates. Those stteel grades have both PSL1 and PSL2 levels. PSL2 has more strict requirements than PSL1. Besides, we also supply API 5L grade A PSL1 and API 5L X80 PSL2 steel.

EN steel grade S275JR material, low alloy high strength steel can meet the requirements of various structures (such as large bridges, pressure vessels, ships, etc.) in engineering. At the same time, it is required to reduce the weight of the structure, improve the reliability and save materials and resources. Low alloy high strength steel is mainly used to manufacture various engineering structures with high strength requirements, such as bridges, ships, vehicles, high pressure vessels, oil and gas pipelines, large steel structures, etc. Because low alloy high strength steel can obtain high strength without complicated treatment process or even heat treatment, the quality of engineering structure is greatly reduced. Therefore, low alloy high strength steel is commonly used to replace the general carbon structural steel.

As the thickness and hardness of EN steel grade S275JR material increase, the tendency to crack at the cutting edge increases. In order to prevent the EN steel grade S275JR material from cutting cracks, preheating should be carried out before EN steel grade S275JR material cutting. Special attention should be paid to preheating to make the entire EN steel grade S275JR material interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole EN steel grade S275JR material cannot be preheated, the partial preheating method can be used instead.

Expect in the EN steel grade S275JR material goods regardless quality be still on the price after-sales service we all will keep in the middle of go together of advantage position real attain the ream customer satisfaction.Our advantage is: experienced craftsmen EN steel grade S275JR material product development technology, excellent production team, hand strict quality control, sales and after-sales service.
