Pipeline steel plate API 5L Gr.B, A573 grade 70 steel sheet, X42, X46, X52, X56, X60, X65, X70, X80 is a key steel material for manufacturing straight-seam submerged arc welded pipe for high-pressure long-distance natural gas pipeline. X80 pipeline steel is currently the highest-grade pipeline steel in engineering application in the world. The our company produced X80 pipeline steel plates are successfully used in natural gas pipeline project with the largest wall thickness and diameter.
Alloy steel plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel. Welding and forming of this steel plate A573 grade 70 steel sheet should be avoided. It is best utilized wherever high resistance to fatigue and or impact is necessary. We can supply ASTM, JIS, DIN and GB various standards alloy steel grades.
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the A573 grade 70 steel sheet steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This A573 grade 70 steel sheet method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.
The automobile steel coil and sheets are one of our main steel materials exported to the overseas. For any questions about automobile steel, for example, JIS G3113 SAPH440 A573 grade 70 steel sheet chemical & mechanical composition, S355MC material specification, S700MC material properties, QSTE 380 TM equivalent, please contact us freely. Our sales person and technician will give you professional answers. And welcome to consult us about automobile steel price.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel A573 grade 70 steel sheet plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
