High strength sa573 gr 58 for bolted and welded structures properties

The company initially focus on providing high-quality steel products to serve for China's rapid infrastructure development. Our company vision is to be the best service provider for iron & steel sa573 gr 58 for bolted and welded structures products globally. To be an innovative business partner for our customers we aim to include sustainability in every aspect of our sa573 gr 58 for bolted and welded structures business. We also provide third-party inspection and approval services and inventory management for our customers.

16MnD5 is a medium carbon quenched and tempered steel with good strength, toughness and hardenability. It can obtain better comprehensive mechanical properties after quenching and tempering. After quality, it has higher fatigue strength and resistance to multiple impacts. Low temperature impact toughness Good, no obvious temper brittleness. sa573 gr 58 for bolted and welded structures product is mainly used to make evaporators, voltage stabilizers, pressure vessels and heads, supporting members, etc. in nuclear power projects

Our company produces ordinary carbon steel sa573 gr 58 for bolted and welded structures with high strength and good plasticity and toughness. Due to the effect of alloy elements, its strength is 25% - 50% higher than that of ordinary carbon steel, its elongation is 15% - 23%, and its impact toughness at room temperature is higher than 60j / cm 2. We have a sa573 gr 58 for bolted and welded structures production line specializing in the production of ordinary carbon steel plate, and strictly control its quality.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium sa573 gr 58 for bolted and welded structures carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some sa573 gr 58 for bolted and welded structures alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.

sa573 gr 58 for bolted and welded structures, ASTM A131 shipbuilding steel has different grade levels. The ordinary strength shipbuilding steel grades are grade A/B/D/E. Their min. yield strength is 235 Mpa, and tensile strength is 400-520 Mpa. The higher strength shipbuilding steel grades are grade AH32/DH32/EH32/FH32, AH36/DH36/EH36/FH36 AH40/DH40/EH40/FH40. The min. yield strength of AH32/DH32/EH32/FH32 steel is 315 Mpa, and tensile strength is 440-590 Mpa. The min. yield strength of AH36/DH36/EH36/FH36 steel is 355 Mpa, and tensile strength is 490-620 Mpa. The min. yield strength of AH40/DH40/EH40/FH40 steel is 390 Mpa, and tensile strength is 510-650 Mpa.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the sa573 gr 58 for bolted and welded structures principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
