SA283 grade C carbon steel plate sheet hot rolled boiler steel plate

45# steel is a common medium carbon quenched and tempered structural steel. The cold plasticity of 45# steel is general. Annealing and normalizing are slightly better than SA283 grade C carbon steel plate sheet quenching and tempering. 45# steel has higher strength and better machinability. After proper heat treatment, 45# steel can obtain certain toughness, plasticity and wear resistance. 45# steel is suitable for hydrogen welding and argon arc welding, not suitable for gas welding.

BEBON has been engaged in the piping industry as a professional manufacturer and supplier of steel plates, ship plates, corten steel, pressure vessels, SA283 grade C carbon steel plate sheet steel pipelines, seamless pipe and ERW pipes since the inception. We provide integrated solutions to whole-package procurement covering miscellaneous ferrous and non-ferrous piping components. The products are widely used in oil & gas project, subsea or offshore platform piping, SA283 grade C carbon steel plate sheet chemical & pharmaceutical pipeline, power plant, sewage treatment, water supply piping, heat exchange application.

SA283 grade C carbon steel plate sheet 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 SA283 grade C carbon steel plate sheet 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. SA283 grade C carbon steel plate sheet annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of SA283 grade C carbon steel plate sheet, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.

Our company regularly visits customers, consults and follows up the after-sales service, and directly solves problems for customers. In the use of our steel materials, whether quality problems or not, the after-sales will help solve the problem as soon as possible. We promise free life-long replacement for any product quality problems. The sound after-sales service system make you free from worries.
