X20Cr13 1.4021 Stainless Spring Steel Strip

AISI420 - X20Cr13 - 1.4021 is a chrome-alloyed heat treatable steel with medium carbon content which is rust proof. 1.4021 has a good corrosion resistance because of its chrome content in moderate aggressive, non chloric substances like soap, solvents and organic acid.

 

Dimensions and tolerances
Thickness: 0.01 to 5 mm; Tolerances: +/- 0.008 to 0.11 mm
Width: 5 to 1219 mm; Tolerances: +/- 0.15 to 0.60
*accept nonstandard size, please contact with our sales.

 

Our Advantage
1. Precise thickness, uniform hardness. Bright surface, smooth edge.
2. High flatness of board surface, high performance after multiple bending.
3. No cracking after stamping, and the quality is stable. And we provide Self-Inspection Reports and Raw-Material Test Certificates.
4. Professional anti-rust protective packaging. On time delivery, competitive price.
5. Large stock available, no MOQ requirement

X20Cr13 1.4021 Stainless Strip Delivery condition

This steel is only hardened by cold rolling. The modulus of elasticity, E , has a value of approximately 21 0 MPa, which cannot be increased by heat treatment.

 

X20Cr13 1.4021 Stainless Strip Surface

In the condition +C, strip shall be delivered with a bright surface (2H), or a rough, matt surface

 

Information to be supplied by the purchaser

The following information shall be supplied by the purchaser at the time of enquiry and order:

a) the quantity to be delivered;

  • the designation of the product form (e.g. strip or cut length);
  • the number of the dimensional standard (EN 10258);
  • the dimensions and tolerances on thickness, width and length according to EN 10258 and, if applicable, letters denoting relevant special tolerances
  • the internal coil diameter according to EN 10258
  • the number of this European Standard (EN 10151);
  • steel name or steel number
  • the delivery condition
  • the type of inspection document in accordance with EN 10204

 

X20Cr13 1.4021 Stainless Strip Internal soundness

The products shall be free from internal defects that could impair their application to a significant extent. Tests appropriate for an assessment of the internal characteristics may be agreed upon at the time of enquiry and order.

 

X20Cr13 1.4021 Stainless Strip Delivery form

Strip is usually supplied in coils. Thin strip may be wound on a supporting centre, made of steel, cardboard or other material, in order to avoid the collapse of the centre. Strip may also be supplied as a spool, in order to increase coil weight, whilst minimising coil outside diameter, in the latter case, any welds shall be clearly marked.

 

Alternatively, strip may be supplied in cut lengths. These may be in a box, or on a pallet, and perhaps strapped together in bundles.

 

Several coils, or bundles of cut lengths, may be assembled on a carrier.

 

Unless otherwise agreed at the time of enquiry and order, the choice of delivery form is left to the discretion of the manufacturer.

 

Unless otherwise agreed at the time of enquiry and order, cold-rolled strip for springs is delivered with the edges. By special agreement, strip can also be supplied with mill edges or with special edges, e.g. machined edges, deburred edges or edges dressed to produce a regular form, usually square or round.

Cold rolled narrow strip of thicknesses up to and including 3 mm in rolled widths fess than 600 mm made from the stainless steel grades. The steels are used in the conditions for the production of springs and spring parts that are exposed to corrosive effects and sometimes slightly increased temperatures.
