At what humidity does a516 grade 70 yield rust?

The company has allocated special environmental protection facilities for all a516 grade 70 yield pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, a516 grade 70 yield steel mill scale, environmental protection dust has reached 100%.

For a516 grade 70 yield, automobile steel sheet materials, it must have excellent pressure-bearing performance. Automobile steel sheets of substandard quality are prone to fracture problems, which also cause waste and consumption of production materials, and directly increase the production cost of automobiles. Generally, the qualified automobile steel sheets used in automobile manufacturing are high-strength steel plates. The high-quality automobile steel sheets are more durable and improve the quality of the entire automobile.

Because a516 grade 70 yield, boiler steel plate is a product of important use, the safety and reliability requirements are strict, and the manufacturing technology is difficult. The boiler steel plate material must have the following main characteristics:The boiler steel plate has high yield strength performance in a certain temperature range (medium temperature and high temperature);The boiler steel plate has sufficient toughness, no brittle failure accident will occur during manufacturing or use.

The yield rate is a comprehensive technical and economic index in the production of medium and heavy plates such as a516 grade 70 yield. Increasing the yield rate can not only reduce the loss of metal, but it is also vital to the economic benefits of the steel enterprise. The influencing factors of the yield of medium and heavy plates are various, for example, the variety structure, negative deviation rolling level, plate shape control level, cutting loss, rolling waste and burning loss, etc.

a516 grade 70 yield, 35CrMo alloy steel is Chinese structual steel. As specified in GBT3077 standard, 35CrMo steel chemical composition should be: Carbon content 0.32-0.40 (C), Silicon content 0.17-0.37 (Si), Manganese content 0.40-0.70 (Mn), Chrome content 0.80-1.10 (Cr), Molybdenum content 0.15-0.25 (Mo). The heating temperature for 35CrMo alloy steel quenching is 850 Centigrade, the cooling material is oil. The heating temperature for 35CrMo alloy steel tempering is 550 Centigrade, the cooling material is oil or water.

The company has a high-quality management, technology and R&D team, and adopts independent research and development, domestic innovative process optimization combination. Relying on advanced manufacturing technology and sophisticated production testing equipment, it has ensured the high quality of products a516 grade 70 yield and won a good reputation. We can offer various kinds of steel materials in GB, ASME, ASTM, JIS, DIN, EN, API standards and specifications.
