Wire 08H18N10 - 1.4301 - aisi 304
Supplier — AvekGlob company — offers sheet and tape, which are made of stainless steel 08H18N10 (AISI 304, 1.4301) at an affordable price from the manufacturer. A timely delivery of metal products to any address specified by the customer is guaranteed.
Stainless steel grade 08H18N10 (the nearest foreign analogues — AISI 304, 1.4301) is a low-carbon austenitic steel, which is specially designed for the subsequent plastic deformation of the initial wire by single- or multiple-drawing or disembarking methods. At the same time, the production of wire from steel 08H18N10 is carried out in accordance with the technical requirements of GOST 9940−81. 304 — the designation of steel in the North American standard AISI, and 1.4301 — the numerical designation in accordance with DIN EN. S30400 — steel number according to UNS specification. The limiting temperature of use of products from these grades of steel is up to 450 0 С (for a short time up to 650 0 С). The wire can be supplied in a solid, semi-solid and soft (after annealing) states.
Urgency of application
Stainless austenitic chromium-nickel steel grades 08H18N10 (AISI 304, 1.4301) have good corrosion resistance (especially in natural gas and liquid environments where there are no significant concentrations of chlorides and salts of hydrochloric acid and salts and seawater) and weldability. The interaction of the wire with salts of other acids should be checked individually. It should be borne in mind that, after welding, the steels in question are unstable to intergranular corrosion. The steels are ductile, and easily amenable to cold deformation, including, with significant degrees of deformation. Wire made of steel 08H18N10 (AISI304, 1.4301) is widely used in the food, oil and chemical industries, as well as in the manufacture of auto parts and fasteners. It is also used in measuring equipment operating at elevated temperatures.
The composition of steel grade 08H18N10 includes the following elements (iron — the rest):
Carbon — not more than 0.08%;
Chrome — 17.0… 19.5%;
Nickel — 8.0… 10.5%;
Manganese — no more than 2%;
Silicon — no more than 1%;
The bound nitrogen is not more than 0.11%.
The amount of metallurgical impurities — phosphorus and sulfur — is limited to 0.045% and 0.015%, respectively. A similar chemical composition has foreign analogues of this material.

Technological features of processing and assortment
The material is good weldability. The strain hardening during cold plastic deformation is relatively small, so no intermediate annealing is performed. To improve the deformability, the material is previously subjected to oxalation.
Stainless steel 08H18N10 (AISI 304 or 1.4301) is supplied both in hot and cold rolled rolled sections, and in the form of finished forgings.
