Analyze The Difference Between P20 Ni And S Steel - China

both aisi p20+ni and aisi p20+s steels are commonly used tool and die steels.

it is also obvious from the grades that these two are added ni or s elements on the basis of p20 - they are equivalent to german standards din 1.2738 and din 1.2312 steel.

p20+ni and p20+s have similarities, but there are also certain differences.

this article will analyze the differences from the chemical composition, performance and application.

p20+ni and p20+s steel chemical composition

the chemical composition of the two steels is basically similar in the content of carbon, silicon, phosphorus and other elements.

the difference is that p20+ni has added ni element to the chemical composition, while p20+s steel has no nickel element.

the presence.

moreover, the s content of p20+s steel is relatively high, and some trace elements are also different between the two.

p20+ni and p20+s steel properties

aisi p20+ni and p20+s steels have a certain impact on the properties of the steel due to differences in chemical composition and process, so their properties will also differ.

the main performance differences are as follows: 1 - p20+ni adds ni element on top of p20+s steel.

the addition of nickel can improve some properties of steel, so compared to aisi p20+s steel, p20+ni has better toughness, plasticity, strength, tempering stability, and toughening effect.

it is more resistant to cracking and fracture during use, improving the stability and service life of manufacturing molds.

2 - the s content of aisi p20s steel is relatively high, sulfur can increase the hardness of steel, and due to the low melting point of sulfur, p20+s steel has good strength and oxidation resistance at high temperatures, so in comparison, p20s steel is easier to cut and process, but p20+ni steel is slightly better than p20+s steel in terms of hardness and strength.

3 - in terms of physical properties, the thermal expansion coefficient of p20+ni is usually low, which means that its size changes less when the temperature changes.

in contrast, p20+s steel has a higher coefficient of thermal expansion.

aisi p20+ni and p20+s steel applications

both steels are widely used in the field of making molds and tools, including plastic molds, extrusion molds and die-casting molds, etc.

din 1.2738 / aisi p20+ni steel is suitable for the manufacture of large, heavy-duty molds, which are used to withstand high impact loads and require better toughness; it is an ideal choice for molds with high requirements for precision and surface quality.

overall, both p20+ni and p20+s steels have various unique performance advantages and application ranges.

there are similarities between the two, but there are also differences.

therefore, when purchasing p20+ni steel or p20+s tool steel, it is important to understand their various information and differences in order to apply them to more suitable steels in projects.
