1.0460 (P250GH) Material Data Sheet

Stainless steel 1.4021 is a rust-resistant, martensitic chromium steel containing 12–14% chromium, which provides solid corrosion resistance. This property can be further improved through surface treatments such as grinding or polishing.

The material is well-suited for use in moderately aggressive, chloride-free environments, such as organic acids, solvents, or soap-based solutions.

Typical applications for 1.4021 include:

• Mechanical engineering

• Hydraulic systems

• Oil and petrochemical industries

Material classification: AISI 420 / 1.4021

• Temperature resistant up to approx. 400 °C

• Good weldability

• Strength: ≥ 250 MPa

The material 1.0460 – P250GH offers good weldability. No special heat treatment is required.

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.
