X2CrNiMo1812 Powder Metallurgy Pressed Parts

Product Introduction

X2CrNiMo18-12

In fact, most people think that stainless steel is impossible to rust. In fact, this concept is wrong, because there is no one that can cope with all corrosive environments, so stainless steel is just difficult to rust. If you have any questions about X2CrNiMo1812 powder metallurgy pressed, please call Qinhuangdao Zhongwei Precision Machinery Co., Ltd.

Material number: 1.4435

Grade: X2CrNiMo18-12

Standard: DIN17400

Main Chemical Composition

① Nickel is one of the main components, which can improve the strength and toughness of steel, and improve hardenability. When the content is high, it can significantly change some physical properties of steel and alloys, and improve the corrosion resistance of steel.

② Chromium is also one of the main components, which can improve the hardenability and wear resistance of steel, and can improve the corrosion resistance and oxidation resistance of steel.

③ Copper is one of the auxiliary alloys, and its outstanding function is to improve the atmospheric corrosion resistance of ordinary low-alloy steel, especially when it is used in conjunction with phosphorus. The essence of the Monel system is a nickel-copper alloy.

④ As one of the auxiliary alloys, molybdenum can significantly improve the hardenability and heat strength of steel, prevent temper brittleness, and improve remanence and coercive force.

The essence of the alloy is nickel-molybdenum alloy.

Heat treatment methods and characteristics

①Solid solution strengthening is an important form of metal strengthening. It is a phenomenon that the strength and hardness of metals are increased by forming solid solutions. When the solute content is appropriate, the strength and hardness of the material can be significantly increased, while the plasticity and toughness are not significantly reduced, which is its biggest feature.

② Aging enhancement is divided into artificial aging and natural aging. Natural aging strengthening is to strengthen the alloy during the process of placing it at room temperature; while artificial aging strengthening is to strengthen the alloy during the process of heating at low temperature. Both are based on the premise of solid solution strengthening, and both are to improve the strength of the alloy.

③Precipitation strengthening is premised on aging strengthening, and the purpose is to strengthen the alloy. Add cobalt, tungsten, molybdenum, and other elements to make the alloy obtain high-yield strength.

④The emergence of grain boundary strengthening is because, at high temperatureS, the grain boundary of the alloy is a weak link, adding trace amounts of boron, zirconium, and rare earth elements can improve the grain boundary strength.

⑤Annealing: The annealed state is the basic state of the furnace. The essence is to transform high-speed steel from austenite to pearlite. The function is to reduce the surface hardness of high-speed steel and improve plasticity to facilitate cold deformation processing such as cutting; to make the composition of steel uniform, improve performance, and prepare for further heat treatment; to eliminate stress to prevent deformation or cracking.
