Application of Medium Carbon High Chromium Corrosion Resistant Martensitic Stainless Steel Elbow

Source: Posted on:2016-12-28 9:40:52

This kind of steel request hardness in 50-55HRC about. Typical stainless steel for the 4Cr13, the steel for the carbon martensitic stainless steel, heat treatment has a higher hardness and wear resistance, and anti-atmospheric and water vapor corrosion, can be used in small plastic mold, quenching available air cooling, To reduce the deformation of the mold heat treatment; and on the larger size of the mold can be used oil quenching, quenching the mold commonly used 200-300 鈩? tempering, tempering hardness of 50-53HRC. Suitable for manufacturing contractor load, high wear and corrosion under the action of the plastic molds.

1Cr17Ni2 steel is a martensitic stainless steel elbow acid-resistant steel, on the oxygen acid (a certain temperature, the concentration of nitric acid, most of the organic acids) and salt aqueous solution has good corrosion resistance; the steel has higher strength and Suitable hardness, but the performance is better than 4Cr13 steel, which requested high corrosion resistance of plastic molds, there are still a part of the use of the model of stainless steel.

1Cr17Ni2 steel quenching temperature range of 950-1050 鈩? oil cooling. After quenching low-temperature tempering or high-temperature tempering properties are better corrosion resistance, after quenching by 200-300 鈩? tempering, steel hardness of 38 manufacturing requirements with a certain corrosion resistance of the plastic mold. The steel quenching temperature is generally selected 1050 鈩?, the steel hardenability, off-40HRC, such as after cold treatment, can continue to transform into austenite martensite, the hardness can be increased to 42-48HRC, steel strength, High hardness, good wear resistance, and a high corrosion resistance. Tempering temperature in the 600-700 鈩?, the fundamental organization of steel for the tempered sorbite, with good strength and toughness with, but also have high corrosion resistance. Stainless steel elbow can also be treated through nitriding, improve wear resistance, anti-occlusal ability and mold service life.
