What is the difference between open flat and original astm a516 grade 70 nace

The company is a leading company that sells astm a516 grade 70 nace steel plate products in the Central Plains region and has a high reputation in the steel plate industry. Since its establishment, the company has always adhered to the business philosophy of "integrity cooperation and common development", and has sold astm a516 grade 70 nace steel products with various materials. The products are widely used in petroleum, chemical, construction, boiler, decoration, offshore operations, electric heating, gravity machinery and other industries.

Q690C steel plates are mainly used in heavy machinery, marine engineering, metal structures. BBN STEEL cooperated with Wugang to produce Q690C steel for use in its enterprise production and construction projects. The prospects for produts exporting to the United States, Canada, Australia, India, and Europe are promising. More than 10,000 tons astm a516 grade 70 nace products have been directly supplied to European customers.

4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. astm a516 grade 70 nace, 4140 steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering treatment, and good low temperature impact toughness. 4140 steel is suitable for manufacturing large and medium plastic mould with certain strength and toughness.

The astm a516 grade 70 nace, heavy steel marine steel plate has the characteristics of pure steel, stable performance and good surface quality, and can be delivered at full scale. The marine steel plates are widely used in the construction of the main structure and superstructure of 10,000-ton ocean-going ships, and can also be used to manufacture the hull structure of inland ships. With the improvement of equipment level and the continuous progress of technology, heavy steel marine plate has made great progress in the production of high-strength shipbuilding steel plates, and its products are extending to the high-end market.

API 5L steel is pipeline steel mainly for use in oil and gas industry. API 5L steel has PSL1 and PSL2 levels. For same API 5L steel grade, the carbon content for PSL1 is higher than PSL2. Meanwhile, the API 5L PSL2 steel has more strict requirement for P, S content than API 5L PSL1 steel, astm a516 grade 70 nace. Therefore, API 5L PSL2 steel strength is higher than API 5L PSL1 steel strength. For example, API 5L X42 PSL2 yield strength is 317-524 MPa, tensile strength is 434-758 MPa. While API 5L X42 PSL1 yield strength is 290 MPa min. , tensile strength is 414 MPa min.
