          Do stainless steel castings must be treated with solid solution?

          From:Changzhou HongHuiHe Machinery Manufacturing Co., Ltd.  Add Time:2018/7/20 13:12:23

          Why should stainless steel castings be treated with solid solution? In fact, it is necessary. If the stainless steel castings are not austenite in the non solid solution treatment, it is easy to produce very serious grain boundary corrosion. As the grain slowly grows up, its strength and hardness will not decrease, which is its mechanical index. As austenitic stainless steel is eliminated through heat treatment to change its mechanical properties, it can be strengthened through cold processing. Then, how do austenitic stainless steel casting be solid solution treatment? In fact, in solid The hardness of the solution is relatively high before solution treatment, and its hardness is low after solid solution treatment, which is due to the full dissolution of many carbides at high temperature.

          Question: on the solid solution treatment of stainless steel

          Answer: grain size, strength and hardness will not reduce this is the mechanical energy index of his own because austenitic stainless steel can not change its mechanical energy through heat treatment, but can be strengthened through cold processing.

          Q: stainless steel solid solution, what's the solution treatment

          Answer: the solution "solution treatment" in the explanation of the tool book heat the alloy to the appropriate degree, keep long enough time to reduce the corrosion resistance. The purpose of solid solution treatment is to eliminate the existing CrC, to reintegrate it into austenite, and to improve the corrosion resistance of austenitic stainless steel. ...

          Q: why should stainless steel have to be treated with solid solution?

          Answer: the stainless steel is a solid solution treatment. The purpose is to improve the plasticity and toughness of the steel and alloy, to prepare for the precipitation hardening treatment, and to make the various phases in the stainless steel alloy fully...

          Question: today's choice

          Answer: but the small editor did not find any questions about the time of the milk powder,... The man SSC is SSC, but the belt has become a stainless steel belt, there is a compass function, the countdown, hour display, the watch of solar watch uses quartz core, stainless steel case.

          Q: what do stainless steel solid solution treatment get?

          Answer: stainless steel solid solution to get what? The problem is very profound, this may be an expert!

          Q: do stainless steel castings must be treated with solid solution?

          Answer: if necessary, if there is no solution treatment, the stainless steel castings are not austenite, and there will be serious grain boundary corrosion.

          Q: how to determine whether stainless steel has been treated by solid solution?

          Answer: cold forming has no solid solution hardness, high hardness, different stainless steel hardness value, dual phase steel high, low austenite.
