1.4919 - aisi 316h pipe, wire, circle

Supplier — AvecGlob Company — offers at a reasonable price from the manufacturer a pipe, circle and wire, which are made of steel AISI 316N (European analog — alloy 1.4919). A timely delivery of metal products to any address specified by the customer is guaranteed.

Technical specifications

Steel grade AISI 316H (1.4919) belongs to the group of austenitic stainless steels austenitic class, which is intended for the primary molding of the original rolling products into forged or stamped products. The material is usually supplied in the annealing state. 316H is a designation according to the AISI standard, 1.4919 — designation according to the European standard DIN EN. S31609 is the UNS specification number.

Steel AISI 316H (1.4919) is a high-carbon version of AISI 316 steel with an increased content of bound nitrogen and boron, which extends the temperature range of its use to 500 0 C. High performance of products made from this steel is also preserved at cryogenic temperatures, and also at a constant stay in the atmosphere of heated air, as well as in contact with various chlorine-containing media.

In the annealed condition, the steel is non-magnetic, and does not harden during heat treatment.

Urgency of application

Products manufactured from AISI 316N stainless steel (1.4919) are used in the chemical industry, in the manufacture of heating equipment parts, as well as gas and oil refining plants. Typical parts made from this steel are the chimneys of industrial plants and refineries, as well as high-temperature installations of the food industry (sugar, vegetable oil, etc.).

Chemical composition

In accordance with the technical requirements of ASTM F138 and ASTM F2181, the steel AISI 316LN (1.4910) includes the following elements (numerical data — in percentages):

Element Minimal content Maximum Content
C 0.01 0.04
