1.4021 (X20Cr13) directly from stock & cut to your required dimensions
1.4021 is a corrosion and acid resistant martensitic chromium steel with good corrosion resistance in moderately corrosive, chloride-free media, such as organic acids, soaps and solvents.
1.4021 is popularly known as AISI 420.
Main application in mechanical engineering, petroleum and petrochemical industry, hydraulic industry.
Machinability: 5 (1 = very bad - 10 = good)
Corrosion class: 1 (0 = weak - 5 = good)
Round, forged, quenched and tempered, machined
Flat, forged, quenched and tempered
The processing with the saw is a mechanical processing of the material, which results in a significantly lower unintended deformation and increased hardness for the existing structure, such as the thermal cutting. Thus, the machined workpiece has a homogeneous structure even at the edge, which does not change in the continuation of the material.
This circumstance allows immediate finishing of the workpiece with milling or drilling . So it is not necessary to anneal the material or make a similar operation beforehand.
