Sheet, plate 08kh18n10t - 1.4541 - aisi 321

Supplier — AvekGlob company — offers sheet and plate made of stainless steel 08H18N10T (AISI 321, 1.4541) at an affordable price from the manufacturer. A timely delivery of metal products to any address specified by the customer is guaranteed.

Technical specifications

Stainless steel grade 08H18N10T (the closest foreign analogues — AISI 321, 1.4541) is a low-carbon austenitic steel, which is specially designed for the subsequent plastic deformation of the starting material into the final product using rolling technologies. Production of sheet and plate of steel 08H18N10T is conducted in accordance with the technical requirements of GOST 9940−81. 321 — the designation of steel in the North American standard AISI, and 1.4541 — the numerical designation according to the European standard DIN EN. S32100 — steel number according to UNS specification.

Adding titanium to the traditional composition of 08Х18Н10 steel provides a significant increase in heat resistance and heat resistance: the maximum temperature of use of the product rises from 450… 500 0 С to 650 0 С, while high values of resistance to long-term strength are preserved at 550 0 С. Rolled steel 08Х18Н10Т (AISI 321, 1.4541) can be supplied in a solid, semi-solid and soft (after annealing) states.

Urgency of application

The main advantage of stainless steel austenitic chromium-nickel steel grades 08H18N10T (AISI 321, 1.4541) — excellent resistance to intergranular corrosion. The resistance of the material to sensitization, combined with its higher strength at temperatures above 500 ° C, makes it a suitable substitute in situations where high strength at high temperatures is required, or the inadmissibility of corrosion of the weld.

Limitations: Steel data are not recommended for use in strongly oxidizing environments. Areas of use are the chemical industry (the production of hot-medium pressure vessel casings), the manufacture of frame / frame equipment for oil and gas processing, etc.

Chemical composition

The composition of steel grade 08H18N10T includes the following elements (iron — base):

Carbon — not more than 0.08%;

Chrome — 17… 19%;

Nickel — 9.0… 12%;

Manganese — no more than 2%;

Silicon — no more than 1%;

Bound nitrogen is not more than 0.1%;

Titanium — up to 0,7%.

The amount of metallurgical impurities — phosphorus and sulfur — is limited to 0.030% and 0.015%, respectively. A similar chemical composition has foreign analogues of this material.

Modulus of elasticity, GPa — 200;

The coefficient of thermal expansion in the temperature range 20… 100 0 С, μm / deg — 16;

The limit of temporary resistance, MPa — 590… 690;

Yield strength, MPa — 220… 350;

Hardness according to Brinell, HB, not more than — 163;

Relative elongation at tension,% — 50… .34.

Technological features of processing and assortment

The steel in question is not recommended for use in welded structures, since the presence of titanium does not make it possible to actively use high-temperature arc welding. In case of overheating, coarsely dispersed carbides are formed in the structure, which reduces the ductility, therefore, the steel grade 08H18N10T (AISI 321, 1.4541) is recommended to deform in the cold state.

These steels are characterized by good deformability and excellent toughness, up to cryogenic temperatures, but they do not lend themselves to mechanical treatment (polishing), therefore they are not recommended for decorative applications.

Stainless steel 08H18N10T (AISI 321 or 1.4541) is supplied both in hot and cold rolled rolled sections, and in the form of finished forgings.

Supplier — AvekGlob Company — offers to buy a sheet or plate that are made of low-carbon stainless steel grade 08H18N10T (AISI 321 or 1.4541) at a price formed on the basis of European and world standards of production. Buy these products can be wholesale and retail. For regular customers, there is a flexible system of discounts.
