304 versus 316 Stainless Steel: Key Differences Explained

304 versus 316 stainless steel

Both 304 and 316 stainless steels are part of the austenitic family of stainless steels, meaning they share a similar crystalline structure and have comparable mechanical properties. However, the difference between 304 versus 316 stainless steel lies in their chemical composition, which significantly affects their performance, particularly in terms of corrosion resistance and overall durability.

Performance comparison between W18 and M2 high-speed steel

W18Cr4V, commonly known as W18, is a tungsten high speed steel known for its excellent hardness, hot hardness and high temperature hardness. The steel contains high levels of tungsten and chromium, as well as vanadium, which together provide excellent wear resistance and red-hardness, and remain sharp even at elevated temperatures.W18Cr4V has a hardness range of 62-65 HRC, a flexural strength of 3.0-3.4 GPa, and a hardness at 600°C of 48.5 HRC.

M2 high-speed steel is a tungsten-molybdenum high-speed steel, favoured for its good machinability. Its hardness ranges from 63-66 HRC, flexural strength is 3.5-4.0 GPa, and hardness at 600°C is 47-48 HRC. Because it contains a high proportion of molybdenum and tungsten, it maintains a high level of hardness while possessing good thermoplasticity and toughness, and it is suitable for the manufacture of hot-forming tools and impact-resistant, structurally weak tools.

Deep comparison analysis of 1.2379 and 1.2080 steels

1.2379,also known as D2,which is a high carbon and high chromium alloy tool steel with high hardness and wear resistance.It contains molybdenum and vanadium,which makes it extremely good in terms of wear resistance.After heat treatment,1.2379 get the features of strong hardenability and good stability of dimension,which is suitable for manufacture large and complex cold working mold require high wear resistance.

1.2080,corresponding to the AISI D3 steel of America,which is a high carbon and high chromium cold working mold steel with high hardness and high wear resistance.Compare with 1.2379,the wear resistance and compressive strength is slightly lower,but more cost-effective.
