90 degree hot pressure elbow is the pipe heating with professional equipment processing molding, and then cut heating to the critical temperature above, insulation for a period of time quickly put into the quenching agent, make its temperature suddenly reduced, faster than the critical cooling speed cooling method made of elbow. The technical parameters of 90 degree hot pressure elbow can be divided into national standard, electrical standard, water standard, American standard, German standard, Japanese standard, Russian standard and so on.

90 degree hot pressing elbow production method

One of the treatment methods: quenching

Quenching is to heat the elbow to the critical temperature above, insulation for a period of time, and then quickly put into the quenching agent, so that the temperature suddenly reduced, faster than the critical cooling speed cooling, and obtain martensite based on the unbalanced structure of the heat treatment method. Quenching increases the strength and hardness of steel, but reduces its plasticity. The commonly used quenching agents are: water, oil, alkali water and salt solution.

Solution two: normalizing

Normalizing is a heat treatment method that heats the hot pressure elbow to the critical temperature and makes all the hot pressure elbow into uniform austenite, and then cools down naturally in the air. Normalizing can eliminate the netted carburizing body in the hot pressing elbow of eutectoid, and for the hypoeutectoid hot pressing elbow, normalizing can refine the lattice and improve the comprehensive mechanical properties.
