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.
EU material from stock.
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.
