Cemented carbide coated rollers are significantly harder than steel, typically several to ten times harder. Advantages of carbide-coated rollers: • HV can reach 900–1500, several times higher than steel • Excellent wear resistance • Good corrosion resistance • High surface stability • Long service life

Stainless steel itself has higher tensile strength and toughness, but compared with chrome plated roller, the hardness of stainless steel roller may be slightly inferior. Therefore, stainless steel rollers may suffer certain wear and tear when operating for a long time or facing high-intensity pressure.

For chrome-plated stainless steel rollers, although the chrome layer can provide strong protection, the chrome plating is not perfect. Excessive chemical erosion, high temperature and wear of the chrome layer itself may cause the coating to fail, exposing the base material of the stainless steel, causing rust or corrosion.

The effect of vinegar's corrosiveness on the chrome plating layer As a weak acidic substance, acetic acid's main function is to decompose rust by chemically reacting with rust. However, acetic acid itself also has a certain corrosive effect on chrome plating.

The chrome coating has a high hardness, usually between 600-800HV (Vickers hardness), while the hardness of stainless steel itself is low, about 150-250HV. Therefore, hardness testing can effectively determine whether the stainless steel roller is chrome-plated.

The main components of stainless steel are alloy elements such as iron, chromium and nickel. The proportion and distribution of these elements determine the corrosiveness and mechanical properties of stainless steel. Chromium, as a key component of stainless steel, has good corrosion resistance. Therefore, the chemical compatibility between stainless steel and chrome plating is good.

Carbon steel is one of the most basic and common types of steel. It is mainly composed of iron and carbon, and the carbon content is usually between 0.2% and 2.1%. According to the carbon content, carbon steel can be divided into low carbon steel (<0.25%), medium carbon steel (0.25%-0.6%) and high carbon steel (>0.6%).

Steel is one of the most common materials for mechanical engraved anilox rollers, especially stainless steel and carbon steel. Due to their strength and toughness, these two types of steel can provide relatively stable performance while bearing high-intensity work.

The steel roller is made of all-steel material and has a solid structure, suitable for high-load and high-precision processing operations; while the rubber roller wraps a rubber layer outside the metal core and mainly relies on the elasticity and flexibility of rubber for material processing.
