When a sufficiently hard abrasive particle strikes steel, it deforms the surface into a valley and pushes up peaks. The distance between the top of the peak and the bottom of the valley is known as the depth profile. In the U.S., the depth profile is measured by mils thousandths of an inch.In the metric system, the micronone millionth of a meter is used.

The stationary blades made of stainless steel were welded to the blade ring made of carbon steel. The blade ring was eroded under the weld, while the weld and the stationary blades were not eroded. In this case, it is recommended to use stainless steel for the parts of the blade ring on which the stationary blades
5160 Spring Steel is a low Chromium alloy steel, with around 0.7 Chromium - which is not enough to make it stainless which requires a minimum of 13 Chromium - but combined with a small amount of silicon 0.2 results in an extremely tough and durable sword and is favored by sword makers such as Angus Trim, Generation 2 and the blades ...

Oct 26, 2001 Stainless steel grade 430 is a non-hardenable steel containing straight chromium, and belongs to the ferritic group of steels. This steel is known for its good corrosion resistance and formability, coupled with practical mechanical properties. It can be used in certain chemical applications due to its resistance to nitric acid.
It could not be forged or ground in the traditional manner, so new machines were introduced to punch out blanks from cold-rolled stainless steel, and heat treat, grind and polish the blades. The increase in mechanised production to meet the demand for stainless steel products meant that many skilled jobs were lost in the interwar period.
