Alloy 42N

Alloy 42N

Steel 42N is a precision alloy with a given TCLE. The main component is iron, which can account for up to 58.8%. The proportion of nickel in the alloy can reach 43%. To a lesser extent, the properties of the material are determined by manganese, silicon, copper, carbon, sulfur and phosphorus.

Special properties

42N with a regulated linear expansion index, at the level of 4.5-5.5 units per degree, in the operating temperature range from -70 to +340 degrees. This allows the use of precision casting and rolled products in almost any climatic conditions, since the products are able to fully retain their shape, volume and properties in the specified temperature range.

Applications

Metal depots in Kyiv offer strip, wire, sheet, strip, rolled products, billets, slabs and blanks from 42H alloy. The material is in great demand in the production of structural elements of electrovacuum equipment, parts of contour measuring instruments that are especially sensitive to sudden changes in temperature, circuit breakers, various relays.

In addition, the alloy is used in the production thermal bimetals, which are the basis for the manufacture of elements that respond to temperature changes.
