Drilling and cutting of CCS grade B salvage ship steel

The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)

Pressure vessel steel SA204GrA, SA204GrB, SA204GrC sheet delivery status: normalized rolling, maybe normalized, or other heat treatment methods may be negotiated with users for delivery. Generally, the thickness of the CCS grade B salvage ship steel, ASME SA204 pressure vessel steel plate is ≤40mm, and it is generally delivered in the rolled state, and the SA204GrA steel plate of more than 40mm can be delivered in the normalized heat treatment state.

CCS grade B salvage ship steel, low alloy high strength steel has good weldability. Welding is the most common method to construct engineering structure, so the steel used in engineering structure requires good welding performance. Low alloy high strength steel has low carbon content, low alloy element content and good plasticity, so it is not easy to produce quenching structure and crack in the weld area, and the addition of Ti, Nb, V can also inhibit the grain growth in the weld area. Therefore, most of the low alloy high strength steels have excellent welding performance and no heat treatment is required after welding.

As the thickness and hardness of CCS grade B salvage ship steel increase, the tendency to crack at the cutting edge increases. In order to prevent the CCS grade B salvage ship steel from cutting cracks, preheating should be carried out before CCS grade B salvage ship steel cutting. Special attention should be paid to preheating to make the entire CCS grade B salvage ship steel interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole CCS grade B salvage ship steel cannot be preheated, the partial preheating method can be used instead.
