Heat treatment process and purpose of S355M steel plate

The company adheres to the S355M steel plate business tenet of "integrity casting strength, cooperation creating win-win", takes value-added service of supply chain as the tenet, and under the premise of existing market, bulk trade, logistics distribution and other advantages, develops a new comprehensive steel industry model combined with informatization. And will continue to provide customers with high-quality steel products and good service. We sincerely welcome new and old customers to join hands with our company S355M steel plate and seek common development!

Because 15CrMo steel contains high content of Cr, C and other alloying elements, the hardening tendency of steel is obvious and the weldability is poor. 15CrMo steel plate is used in petroleum, petrochemical, high-pressure boilers, etc., seamless pipes for special purposes include seamless pipes for boilers, seamless steel pipes for geology, seamless pipes for petroleum, etc. Welcome to contact us for S355M steel plate product price in 2020.

The S355M steel plate processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the S355M steel plate steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.

Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the S355M steel plate plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.

S355M steel plate, 35CrMo alloy steel is Chinese structual steel. As specified in GBT3077 standard, 35CrMo steel chemical composition should be: Carbon content 0.32-0.40 (C), Silicon content 0.17-0.37 (Si), Manganese content 0.40-0.70 (Mn), Chrome content 0.80-1.10 (Cr), Molybdenum content 0.15-0.25 (Mo). The heating temperature for 35CrMo alloy steel quenching is 850 Centigrade, the cooling material is oil. The heating temperature for 35CrMo alloy steel tempering is 550 Centigrade, the cooling material is oil or water.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent S355M steel plate products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the S355M steel plate technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
