X5CrNi18-10 1.4301 Stainless Spring Steel Strip

DIN EN 1.4301 stainless steel (X5CrNi18-10) is a conventional austenitic stainless steel with good resistance to atmospheric, organic and inorganic chemicals. This material is widely used due to its excellent intergranular corrosion resistance, good cold deformability, good deep drawability and weldability.

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

X5CrNi18-10 1.4301 Stainless Strip Mechanical properties

X5CrNi18-10 1.4301 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.

X5CrNi18-10 1.4301 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

X5CrNi18-10 1.4301 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.

X5CrNi18-10 1.4301 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.

1.4306 (X2CrNi19-11) and 1.4307 (X2CrNi18-9) are ultra-low carbon versions of 1.4301. The purpose is to improve the corrosion resistance after welding and prevent carbide precipitation caused by stress relief for a long time.
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.

For over 20 years, Fushun Steel, have been dedicated to manufacturing high-quality spring steel wire. Our stable quality and superior technique are the foundations of our success, and we pride ourselves on delivering products that meet or exceed our customers' expectations. With a focus on innovation and efficiency, we utilize the latest technologies to ensure consistent quality and timely delivery.

We have more than 400 employees and our plant covers an area of nearly 15,000 square meters, with an annual output of 100,000 tons. Our advanced equipment allows us to produce high-quality spring steel products efficiently, meeting the needs of our customers.

In the production of spring steel wire, a variety of specialized equipment is essential. Shot Peening Machine. Wire Drawing Machine. Phosphating Equipment. Annealing Furnace. Polishing Equipment. Wire Coiling Machine. End Grinding Machine. Tensile and Compression Testing Machine.

Our commitment to excellence and reliability has resulted in long-standing partnerships with some of the biggest names in the industry. Like MW Industries, NHK Spring, Scherdel, Sogefi, Mubea etc. We also have established partnerships with several prominent Chinese steel groups, like Baowusteel, Xinyusteel, Nanjinsteel, Shagang etc.

Our spring steel wire comes in various categories such as music wire, hard drawn wire, oil tempered wire, chrome silicon wire, chrome vanadium wire, stainless steel wire, nickel plated wire, phosphate coated wire, galvanized wire, and copper coated wire.

Spring steel wire is a versatile material that is utilized in the manufacture of a wide array of products. including automotive suspension springs, valve springs, and torsion springs. Beyond springs, paper clips and mattress supports. In addition, spring steel wire is essential in the creation of retaining rings and circlips that are utilized to secure components on shafts or within bores, and in making various types of fasteners. The durability and resilience of spring steel wire also make it a key material in the manufacturing of certain types of cable, fencing, and even some musical instruments, such as piano and guitar strings, where its ability to return to its original shape after deformation is highly valued.
