Detailed introduction

The raw materials of stainless steel cable trays are made of stainless steel plates of different models. (Stainless steel cable trays are usually made of 201 stainless steel and 304 stainless steel.) The surface generally does not need to be treated. The strength and corrosion resistance of stainless steel cable trays are higher than ordinary bridges. a lot of. Now the development of stainless steel has made stainless steel's corrosion resistance, appearance, workability, strength and other characteristics far exceed other materials.

Features:

Stainless steel cable tray (anti-corrosion) has the characteristics of simple structure, novel style, large load, light weight, corrosion resistance, long service life, easy installation and so on.

Scope of application:

The stainless steel cable tray has the advantages of strong corrosion resistance, high bearing capacity, high tensile strength, and good mechanical properties, such as sulfuric acid, nitric acid, alkali, nitrate and alkali. Got perfect. It is suitable for general environmental areas, and can show its unique anti-corrosion performance in coastal fog areas, high humidity and corrosive environments.

Stainless steel bridge is suitable for laying large diameter cables, especially for high and low voltage power cables.

Stainless steel bridges are divided into 201 materials, 304 materials, and 316 materials.

201 stainless steel cable tray

201 stainless steel, has the characteristics of acid resistance, alkali resistance, high density, polishing without bubbles, no pinholes, etc. It is a high-quality material for the production of various watch cases and strap bottom covers. It is mainly used to make decorative pipes, industrial pipes, and some shallow-stretched products. 201 stainless steel plates have similar resistance to general corrosion as the unstable nickel-chromium alloy 304. The long-term heating of 201 stainless steel plate in the temperature range of chromium carbide may affect the alloy 321 stainless steel plate and 347 in harsh corrosive media. 201 stainless steel plate is mainly used in high temperature applications. High temperature applications require strong anti-sensitization of the material to prevent intergranular corrosion at lower temperatures.

Uses of 201 stainless steel plate

It is used in chemical, coal, and petroleum industry outdoor and open-air machines with high requirements for resistance to grain boundary corrosion, heat-resistant parts for building materials, and parts with difficult heat treatment;

Chemical composition of 201 stainless steel plate bridge

chemical composition(%):

Chemicai composition (WT%)

(C) Carbon: ≤0.15 (Si) Silicon: ≤0.75 (Mn) Manganese: 5.5 ~ 7.50 (Cr) Chromium: 16.0 ~ 18.0

(N) Nitrogen: ≤0.25 (Ni) Nickel: 3.50 ~ 5.50 (P) Phosphorus: ≤0.060 (S) Sulfur: ≤0.030

316 stainless steel cable tray

316 stainless steel, 18Cr-12Ni-2.5Mo Due to the addition of Mo, its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good, which can be used under harsh conditions; excellent work hardening (non-magnetic). Equipment for seawater use, chemical, dye, papermaking, oxalic acid, fertilizer and other production equipment; photographs, food industry, facilities in coastal areas, ropes, CD rods, bolts, nuts. Chemical composition of 316 stainless steel: C ≤ 0.08, Si ≤ 1.00, Mn ≤ 2.00, P ≤ 0.035, S ≤ 0.03, Ni: 10.0-14.0, Cr: 16.0-18.5, Mo: 2.0-3.0. 316 stainless steel mechanical properties, tensile strength Strength (Mpa) 620 MIN, yield strength (Mpa) 310 MIN, elongation (%) 30 MIN, area reduction (%) 40 MIN, density of 316 stainless steel 8.03 g / cm3, austenitic stainless steel generally use this value

Corrosion resistance

The corrosion resistance is better than 304 stainless steel, and it has good corrosion resistance in the production process of pulp and paper. And 316 stainless steel is also resistant to marine and aggressive industrial atmospheres

304 stainless steel cable tray

304 stainless steel is a universal stainless steel material, and its rust prevention performance is stronger than that of 200 series stainless steel materials. High temperature resistance is also good, and the general temperature limit is less than 650 ° C. 304 stainless steel has excellent stainless corrosion resistance and good resistance to intergranular corrosion. For oxidizing acids, 304 stainless steel has strong corrosion resistance in nitric acid with a concentration ≤65% below the boiling temperature. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.

304 stainless steel performance

System description: 304 stainless steel is the most widely used chromium-nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; good hot workability such as stamping and bending. , No heat treatment hardening phenomenon (non-magnetic, so use temperature -196 ℃ ~ 800 ℃). Corrosion resistance in the atmosphere. If it is an industrial atmosphere or heavily polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. Has good processability and solderability. Plate heat exchangers, bellows, household products (class 1, 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molded products), medical appliances, building materials, chemicals, food industry , Agriculture, ship parts, etc. 304 stainless steel is a nationally recognized food-grade stainless steel.

304 stainless steel chemical grade is 06Cr19Ni10 old grade (0Cr18Ni9) containing 19% chromium, 8-10% nickel.

304 stainless steel is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, general chemical equipment, nuclear energy, etc.

Chemical composition of 304 stainless steel:

C Si Mn PS Cr Ni (nickel) Mo

SUS304 chemical composition ≤0.08 ≤1.00 ≤2.00 ≤0.05 ≤0.03 18.00-20.00 8.00 ~ 10.50
