Delivery status: Generally, it is delivered in a heat treatment state, and the type of heat treatment is specified in the contract; if it is not specified, it is delivered in a non-heat treatment state.

How is the welding of Y3Cr13 stainless steel?

Y3Cr13 stainless steel, containing added elements such as nickel, molybdenum, vanadium, etc., is mainly used to increase the limited allowable working temperature of standard steel to higher than 1100K. When these elements are added, the carbon content also increases. With the increase of carbon content increases, the problem of avoiding cracking in the hardened heat-affected zone of the weld becomes more serious.

Y3Cr13 stainless steel can be welded in the state of annealing, hardening and hardening and tempering. Regardless of the original state of the steel, a hardened martensitic zone will be produced near the weld bead after welding. The hardness of the heat-affected zone mainly depends on Depending on the carbon content of the base metal, when the hardness increases, the toughness decreases, and this area becomes more prone to cracks. Preheating and controlling the interlayer temperature are the most effective ways to avoid cracks. nature, post-weld heat treatment is required.

What are the characteristics of Y3Cr13 stainless steel?

Y3Cr13 stainless steel is a type of stainless steel whose properties can be adjusted by heat treatment (quenching, tempering). Generally speaking, Y3Cr13 stainless steel is a type of hardenable stainless steel. This characteristic determines that this type of steel must meet two basic conditions: one is that there must be an austenite phase region in the equilibrium phase diagram, and heating for a long time within the temperature range of this region makes the carbides dissolve into the steel After that, quenching is carried out to form martensite, that is, the chemical composition must be controlled in the v or v ū phase region, and the second is to make the alloy form a corrosion-resistant and oxidation-resistant passivation film, and the chromium content must be above 10.5%.

How is 1Cr13 stainless steel processed? 

Generally, stainless steel structural parts are often quenched and tempered to obtain high comprehensive mechanical properties.

The ferrite of 1Cr13 is minimized in the temperature range of 950°C-1100°C. Therefore, the quenching heating temperature is preferably 980°C-1050°C. organization after quenching. It is a small amount of ferrite + low carbon martensite. 2Cr13 can obtain a single-phase austenite structure at a temperature of 950°C-1150°C, and can obtain a martensite structure + a very small amount of retained austenite after quenching.

Tempering: 1Cr13 is 650°C-700°C, 2Cr13 is 640°C-700°C, tempered sorbite.
