Alloy carbon BV DH32 oil tanker steel used in construction

ASTM A387 Grade 91 BV DH32 oil tanker steel is a high level steel grade for outstanding heat and anti corrosion and oxidation resistance characteristics, it BV DH32 oil tanker steel satisifies most applications in fierce working environment with higher requirements.

The company now has BV DH32 oil tanker steel oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than BV DH32 oil tanker steel 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of BV DH32 oil tanker steel, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

The common delivery status of BV DH32 oil tanker steel, SA516 Gr 70 plate is as follows:
1) SA516 Gr 70 plate quenching: the process of rapid cooling after heating to the temperature above the phase transformation point.
2) SA516 Gr 70 plate normalizing: after heating above the phase transition temperature, it is cooled normally (in air).
3) SA516 Gr 70 plate annealing: heating to above the phase transition temperature, cooling slowly.
4) SA516 Gr 70 plate tempering: after quenching, it is heated to a certain temperature (lower than the quenching temperature), kept warm, and then cooled.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
