Why we need to adjust the iron liquid of hot rolled RA 40 hull steel plate

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for hot rolled RA 40 hull steel plate various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several hot rolled RA 40 hull steel plate after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

A633Gr.C,D steel plate A537CL1/A633Gr.C,D steel plate, under ASTM-SAE standard A537CL1/A633Gr.C,D steel plate, under ASTM-SAE standard, we can regard hot rolled RA 40 hull steel plate, A537CL1/A633Gr.C,D steel plate as Fine-grain structural steels, normalised rolled steel. A537CL1 steel plate is one mainly of Fine-grain structural steels, normalised rolled steel,A537CL1/A633Gr.C,D steel plate is under ASTM-SAE standard equivalent to DIN:TStE355, EN:S355NL, which with a minimum impact energy of 20J at temperatures not lower than -20 degree and the tensile strength of A537CL1/A633Gr.C,D is 4800 to 620 MPa.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for hot rolled RA 40 hull steel plate, 42CrMo steel is quenching and tempering.

Difference between Q345R boiler vessel plate and ordinary Q345 plate, hot rolled RA 40 hull steel plate:Q345R boiler vessel plate is pressure vessel steel, Q345 plate is low alloy steel.Q345R boiler vessel plate generally requires flaw detection and positive deviation, while Q345 plate generally has lower requirements.In terms of performance, Q345R boiler vessel plate and Q345 plate are of the same level. However, due to high requirements, they can not be mixed in general.Generally, the requirement of Q345R boiler vessel plate is higher than Q345 plate, hot rolled RA 40 hull steel plate.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.

The strip steel thickness is generally below 6mm, which is convenient for crimping and processing. You should choose the hot rolled RA 40 hull steel plate, strip steel specifications according to your own purposes. The specifications and materials used for different purposes are different, so you must confirm it before buying. It is best to ask professionals to give advice before purchasing strip steel, and purchase the specifications and types you need according to the corresponding requirements.
