The heat treatment knowledge of S690QL mechanical properties

S690QL mechanical properties, Alloy steel plate can be used for machining machinery and equipment. The requirement of the equipment to the steel plate is very high, so the alloy steel plate is mostly used to manufacture the mechanical equipment. The alloy steel plate can also be used as raw materials for fastening hardware. Nuts and bolts are used in a complex environment, so there must be certain requirements for strength and high temperature resistance. Otherwise, if fracture occurs, it will lead to accidents and cause a series of irreparable consequences.

Weathering steel plates have an excellent corrosive resisting property like resistance to crevice and pitting corrosion, resistance to corrosion and oxidation. This plate also has resistance to chloride corrosion cracking and stress corrosion. These plate are not affected very easily by acids and environmental rust and works in the sulfide atmosphere. S690QL mechanical properties, Weather resistant steel plates have excellent workability, formability, easy to install, easy to fabricated, machinability, durability, reliability.

Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.

We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
