A633 Grade C bolted construction equivalent grade in China

A633 Grade C bolted construction 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 A633 Grade C bolted construction 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. A633 Grade C bolted construction annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

A633 Grade C bolted construction surface cracks refer to the linear cracks on the surface of A633 Grade C bolted construction, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: A633 Grade C bolted construction surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.

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.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.

Advanced typical figures and typical deeds are the embodiment and symbol of A633 Grade C bolted construction enterprise spirit, outstanding ideas and vivid images, with strong demonstration, radiation and transmission effect. Without distinctive typical characters, there is no unique enterprise culture. In carrying out the construction of enterprise culture, the advanced enterprise culture should be typified. Vigorously excavate, discover, cultivate and summarize the company's A633 Grade C bolted construction advanced models.

Expect in the A633 Grade C bolted construction goods regardless quality be still on the price after-sales service we all will keep in the middle of go together of advantage position real attain the ream customer satisfaction.Our advantage is: experienced craftsmen A633 Grade C bolted construction product development technology, excellent production team, hand strict quality control, sales and after-sales service.
