Heat treatment is a very important process to improve the performance of abs grade a EH36 marine plate etc. metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the required structure and properties.
India's Ministry of abs grade a eh36 marine plate steel has extended the deadline for steel product certification from April 23 to three months as the Bureau of standards (BIS) has closed factories and laboratories due to the current blockade and travel ban. According to the order of the Ministry of Commerce, "the implementation date of the following Indian Standards is extended for three months after April 23, according to the notice of the order for abs grade a eh36 marine plate steel products 2000."
The weldability of abs grade a eh36 marine plate is good. It means that under certain process and construction conditions, abs grade a eh36 marine plate can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.
This European Standard EN 10225 specifies requirements for weldable structural steels to be used in the fabrication of fixed offshore structures in the form of plates abs grade a eh36 marine plate up to and including 150 mm thick. It also specifies sections up to 63 mm thick except for sections delivered in the as-rolled condition which are permitted up to 25 mm thick only.
