Shaped carbon steel a 573 gr 70 carbon-manganese-silicon steel

Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.

Q690D grade is a low-alloy high-strength structural steel, belonging to the structural steel category. Q690D steel plate executive standard: GB/T16270-2009. Q is the expression of yield strength, 690 is its lower limit yield value, and D is its grade. This grade also has a higher yield strength and tensile strength. Q690 series grades also include Q690C, Q690D, Q690E, Q690F. Delivery status of steel a 573 gr 70 carbon-manganese-silicon steel: It should be delivered in quenched and tempered state. In addition, this grade can be delivered according to some special requirements of customers, but it should be indicated in the contract.

a 573 gr 70 carbon-manganese-silicon steel annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of a 573 gr 70 carbon-manganese-silicon steel annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. a 573 gr 70 carbon-manganese-silicon steel annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
