What are the quality requirements of JIS SM490A plates

The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.

JIS SM490A plates,According to the European standard EN10025-3:2004, S275NL weldable fine grain structural steel is mainly used to manufacture the plants of factory, the common construction and construction machinery and equipment. For the bound technical terms,steel plate S275NL have to be done low temperature impacting test in rolling process at -50℃ with minimum energy 27J. Other additional requirements such as UT shall be according to EN 10160, and customers can choose the relative classes for Ultrasonic test.

JIS SM490A plates,Weather-resistant steel plate has excellent hot-rolled steel plate with resistance to sulfuric acid dew point corrosion. Its superior sulfuric acid dew point corrosion resistance and very high cost performance are the best materials that can completely replace stainless steel and surpass stainless steel (in terms of sulfuric acid dew point corrosion resistance). ND steel has great economic significance and is in line with today's high efficiency, long life and energy saving.

JIS SM490A plates,The purpose of alloying Q345B steel is to use the interaction of alloy elements with iron and carbon and the effect on iron-carbon phase diagram and the heat treatment of steel to improve the structure and properties of steel Interaction of alloying elements with iron and carbon: After alloying elements are added to steel, they mainly exist in steel in three forms That is: forming a solid solution with iron; forming carbides with carbon; and possibly forming intermetallic compounds in high alloy steels,JIS SM490A plates.

"Adopt standard specification: ASTM, JIS, EN, DINCategory: Structural Steel, carbon steel plate, hot rolled plateCarbon steel plate specification: Thickness: 1mm to 200mm; Width: 1500mm to 3500mm: Length: 3000mm to 27000mmThird Party Inspection: ABS, DNV, BV, GL, CCS, LR, RINA, KR, NK, CE, SGS, IKE, IEI or other quality department."

Expect in the 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 product development technology, excellent production team, hand strict quality control, sales and after-sales service.
