Specify X30Cr13 identity explicitly
1.4028 identifies X30Cr13 within the wider 420 family. It should not be ordered as the same material as 1.4021 or 1.4034. Using the full EN number instead of a broad family name reduces purchasing ambiguity, particularly for components with defined hardness or heat-treatment requirements.
Consider hardness and machining together
Supply condition affects tooling behaviour and subsequent operations. Separate a request for annealed or quenched-and-tempered stock from the finished component requirement. State section, finished size, grinding or polishing allowance and acceptance condition. Planned welding requires assessment of suitable procedures and heat treatment for martensitic material.
Typical application areas
Cutting parts, mechanical equipment, wear-exposed components.

Frequently asked questions
Can I request 1.4028 in cut lengths?+
Share your required section, dimensions and quantity. Our team will assess suitable supply and cutting options for the specific grade.
Are the listed grade designations interchangeable?+
Designation systems can overlap, but they do not make every specification identical. Use the exact standard and certificate requirements defined by your project.
