The alloy elements in ASTM A387 pressure vessel steel sheet

Do you know the thickness range of BBN Steel's hydrogen sulfide resistant steel plate? The ASTM A387 pressure vessel steel sheet product thickness is between 8-180mm. Q345RHIC steel and Q345RR-HIC test environment: A solution HIC steel (HIC-A) and B solution HIC steel (HIC-B) Q345RHIC and Q345RR-HIC test items: tensile, bending, thickness direction properties, grain size, Brinell Hardness, ultrasonic flaw detection, HIC test, impact test, high temperature tensile test, SSCC test, melting analysis, finished product analysis.

The company has ASTM A387 pressure vessel steel sheet advanced production equipment and machining technology, excellent marketing team and domestic regional channel partners, and sound management plan for product market development and after-sales service. After years of cooperation experience ASTM A387 pressure vessel steel sheet, we have accumulated a large number of customers at home and abroad, and won unanimous praise.

Plasma cutting has a wide range of applications. With different working gas, it can cut various kinds of metals that are difficulty to handle by oxygen cutting. Plasma cutting is fast and efficient when cutting metal with small thickness. The ASTM A387 pressure vessel steel sheet cutting speed can reach more than 10m/min. Plasma cutting can get a clean, neat, non stick slag cutting surface, while the deformation and thermal effect of the incision are small, its hardness change is little, and the cutting quality is good.

ASTM A387 pressure vessel steel sheet, Q345B low alloy steel plate composition:
1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%;
2) Add manganese-based alloying elements;
3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel;
In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.

The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel ASTM A387 pressure vessel steel sheet products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
