20G steel is boiler steel, which is similar to No. 20 carbon steel. The difference is that 20G steel has higher and stricter inspection standards than ABS E40 hull structural steel, No. 20 carbon steel for harmful impurities and internal defects. That is to say, 20G steel is specially produced for boiler pressure vessels. It is special purpose "No. 20 carbon steel". The use of 20G steel to make boilers is not because it is more resistant to burning than other steels such as ABS E40 hull structural steel, but because of its strength, toughness, ductility, weldability, temperature influence, fatigue fracture, price and cost, etc. 20G steel is most suitable for use in medium and low pressure boilers.
The location weld of ABS E40 hull structural steel, wear-resistant steel plate is only allowed to be welded on the base metal surface with the electric welding rod for welding the base metal; in the welding of the base course, the base weld shall be strictly prevented from melting to the transition layer or even the multiple layer weld of stainless steel, so as to prevent a small amount of high chromium and high nickel surfacing wear-resistant steel plate components diluted into the carbon steel weld to form martensite structure and harden.
