The heat treatment knowledge of xar 400 steel plate

The difference between application of 20# steel and Q345 steel. 20# steel is mainly used for making parts, which can be heat treated; Q345 steel is mainly used for making engineering structural parts, which is usually not heat treated. Q345 steel does not emphasize the composition, but its yield strength must be above 345mpa. Because the composition xar 400 steel plate is not fixed, Q345 steel is difficult to heat treatment (the temperature and time control of heat treatment are related to the composition, and different components use different processes).

In terms of service, our service is a "one-stop" way of working. We have our own xar 400 steel plate processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as xar 400 steel plate cutting, welding, drilling, galvanizing, etc., at the lowest cost.

The company selects steel raw materials and controls every quality link from the source to ensure high quality. Each process is strictly checked to ensure that there is zero failure rate in the customer's on-site use. Provide customers with high-quality xar 400 steel plate products and services with an innovative spirit and work together with customers to create a better future. The company can process and cut various special-shaped parts according to customer needs, and can also customize futures of various material specifications according to requirements.

The effect of Q345B alloy steel plate on the mechanical properties in the annealed state. The strengthening effect of alloying elements on steel in the quenched and tempered state, because it fully utilizes all four strengthening mechanisms. Martensite is formed during quenching, and carbide is precipitated during tempering, resulting in a strong second-phase strengthening, and at the same time greatly improving the toughness. Therefore, obtaining martensite and tempering it is an economical and effective comprehensive strengthening method for steel such as xar 400 steel plate.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
