Introduction to Stainless Steel Wire Rope

Stainless steel wire is a kind of silk products with different specifications and models made of stainless steel. The common stainless steel wires with good corrosion resistance and high cost performance are 304 and 316 stainless steel wires.

The types of stainless steel wire rope are generally divided into 2 series, 3 series, 4 series, 5 series and 6 series stainless steels according to austenite, ferrite, two-way stainless steel and martensitic stainless steel. 316 and 317 stainless steels (see the performance of 317 stainless steel below) are molybdenum containing stainless steels. The molybdenum content in 317 stainless steel is slightly higher than that in 316 stainless steel. Because of the molybdenum in the steel, the overall performance of this steel is better than 310 and 304 stainless steels. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses. 316 stainless steel also has good chloride corrosion resistance, so it is usually used in marine environment.

Type and use: There are many classification methods for stainless steel wire rope, and different countries have different classification methods. The common classification methods are according to the structure, twist direction, surface, use, strength, etc. of the wire rope. The diversity of varieties reflects the diversity of uses. Edit the classification of this paragraph a. According to the contact state of the adjacent layers of steel wire in the strand, the stainless steel wire rope can be divided into three basic structural forms: point contact stainless steel wire rope, line contact stainless steel wire rope, and surface contact stainless steel wire rope. b. According to the form of strand section, stainless steel wire rope can be divided into round strand stainless steel wire rope and special-shaped strand stainless steel wire rope (wherein special-shaped strand stainless steel wire rope mainly includes triangular strand stainless steel wire rope, elliptical strand stainless steel wire rope and sector strand stainless steel wire rope). c. According to the surface state of steel wire (steel wire rope), steel wire rope can be divided into smooth stainless steel wire rope, galvanized stainless steel wire rope (zinc aluminum alloy) and plastic coated stainless steel wire rope. Edit the lay properties of this section

1. Point contact: the adjacent layers of steel wires in the strand are in the form of point contact. Except for the central steel wire, the diameter of each layer of steel wire is equal, and the strand is formed by layered twisting.

2. Wire contact: the adjacent layers of steel wires in the strand are in linear contact form, and the strand is made of steel wires with different diameters at one time.

3. Surface contact: the adjacent layers of steel wires in the strand are in the form of surface contact.

4. Point and line contact stainless steel wire rope: there are two contact forms of point and line between adjacent layers of steel wire in the strand. Strands are made of steel wires of different diameters by twisting in several times.

5. Irregular strand stainless steel wire rope: it is named because its strand section is triangular, elliptical or fan-shaped.

6. Galvanized stainless steel wire rope: stainless steel wire rope made by galvanizing the surface of the wire (or drawing after galvanizing) and then twisting.

7. Twisting direction of stainless steel wire rope: The so-called twisting direction of wire rope (or strand) refers to the direction of spiral wire twisted by strand in the rope (or wire in strand). Judgment method: place the rope (or strand) vertically for observation. If the spiral rising direction of strand (wire) is from left to top, it is left twisting, which can be represented by "". According to the laying direction of strands and ropes, the steel wire ropes are divided into: a right cross lay stainless steel wire ropes: right lay ropes, left lay ropes; b left cross lay stainless steel wire ropes: left lay ropes, right lay ropes c right lay stainless steel wire ropes: right lay ropes, right lay ropes d left lay stainless steel wire ropes: left lay ropes, left lay ropes e right mix lay stainless steel wire ropes: right lay ropes, some left lay ropes, Some strands are twisted right f some strands are twisted left stainless steel wire rope: the rope is twisted left, some strands are twisted right, and some strands are twisted left Edit this section of rope core and code a fiber core (natural or synthetic): FC, such as FC stainless steel wire rope. B Natural fiber core: NF, such as NF stainless steel wire rope. C Synthetic fiber core: SF, such as SF stainless steel wire rope. D Wire rope core: IWR (or IWRC), such as IWR stainless steel wire rope. E Wire strand core: IWS, such as IWS stainless steel wire rope. Edit the feature of this section A. The dimensional accuracy is high, up to ± 0.01mm; B. Good surface quality and brightness; C. Strong corrosion resistance, high tensile strength and fatigue strength; D. Stable chemical composition, pure steel, low inclusion content; The package is intact and the price is favorable; The stainless steel wire rope used in this section has many characteristics such as high temperature resistance, good fatigue resistance, excellent breaking force, long service life, durability, etc. It is widely used in coal, petroleum, metallurgy, chemical industry, ships, bridges, power, rubber, military, tourism, water conservancy, light industry and other industries. The products can be produced according to international standards such as ISO, BS, DIN, JIS, ABS, LR, etc
