Composition

Steel strip grade 20X23H18 (AISI 310s) is made of austenitic grade alloy, resistant to soil and atmospheric moisture, aggressive industrial gases. According to GOST 5632−72 the main alloying element is chromium in the amount of 22−25%. Corrosion resistance increases with the increase of its share. 17% Cr makes the steel resistant in the aggressive oxidizing environments. 12−15% Ni in the composition gives the necessary ductility and increases heat and corrosion resistance. In addition, the alloy is alloyed with 2% Mn, 1% Si, 0.2% C, thousandths of a percent phosphorus and sulfur.

Production

Tape is produced in accordance with GOST 4986−79, strip in accordance with GOST 4405−75 and GOST 103−76. Tape may be produced soft and also pressed. Ribbon of foreign production AISI 310s is produced in coils 60−1500 mm wide. It should be noted that the weight of such coils is rather large. Tape thickness is 0,05−28 mm, width — 2−1000 mm. Fastening tape from alloy 20Х23Н18 AISI 310s has 20±0,5 mm width, 0,05−28 mm thickness, not less 5 кН breaking load, 0,12−0,13 kg/m. This type of tape is used as a specialized dimensionless «clamp», which after tightening with a specialized tool on the site is fixed with a lock.

Application

Stainless steel bands are used for fasteners, anchoring and intermediate clamps, brackets and necessary components for transmission line supports, fastening of compressors to overhead lines, fixing heating cables on oil pipelines etc. Such bands are used for production of fences, springs, cutlery and in household appliances. In the automotive industry — for the manufacture of body parts. In the field of design — for decorative furniture design. An important advantage of 20X23H18 tape is the ability to produce different parts from a single roll. Scraps are also used, for example, for small parts to order or for other purposes, which helps to save material.
