The use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight. It must be noted that for components that may be bent, the allowable stress must be corrected to ensure the robustness of the structure. Sometimes low-alloy high-strength steel is used to replace a633 alloy steel and a36 carbon steel, carbon structural steel without changing the cross-sectional size. Its sole purpose is to obtain a stronger and more durable structure without increasing weight.
, 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.
Our company will accept the product quality objection registration record, pass it to the production unit and relevant departments, and timely coordinate the supervision of product quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
The company will also put Georgetown steelworks on "care and maintenance mode" and temporarily lay off or redeploy about 130 employees working at the steelworks and contractors while some maintenance employees will be on staff during the closure. It is stated that unemployment insurance and state-based unemployment support will be available immediately to workers affected by these changes.
