Product description

304 stainless steel flat bars, is a corrosion-resistant, high temperature resistance to creep strength of alloy steel material.

Excellent pitting resistance, high temperature creep strength excellent.

304 flat steel is one of the steel, 304 flat steel generally divided into hot-rolled flat steel and cold-drawn flat steel. The general delivery status of hot rolled 304 flat steel surface is pickling, and the surface of Cold-drawn 304 flat steel is in general delivery condition for brushed polishing.


Characteristics

1) cold-rolled pflat baruct appearance luster is good, beautiful;

2) because of the Shanghai World Strong (SHSQBXG) Stainless steel material factory add mo, corrosion resistance, especially pitting corrosion performance excellent;

3) Excellent high temperature strength; turn from "I Want stainless steel"

4) Excellent processing hardening (weak magnetic after processing)

5) The state of solid dissolved non-magnetic;

6) compared with 304 stainless steel, the price is higher.


Scope of application

Pipeline, heat exchanger, food industry, chemical industry, etc.

Application

1. Household sink 2. Medical Products 3. Stainless Steel Valves

 

304 Stainless steel density 7.93 g/cm3 austenitic stainless steels generally use this value

304 Chromium content (%) 18--20.

304 is equivalent to China's 0cr19ni9 (0CR18NI9) stainless steel, 304 stainless steel is a versatile stainless steel material, anti-rust performance than 200 series of stainless steel material to be strong. High temperature resistance is also better, can be up to 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance. In the experiment: 304 stainless steel material concentration ≤65% The boiling temperature below the nitric acid, has the very strong corrosion resistance. The alkali solution and most organic acids and inorganic acids also have good corrosion resistance.


Common Pflat baructs, Specifications & Standards

GB/T2101 - 89 (general provisions of steel acceptance, packing, marking and quality certification); GB9787-88/GB9788-88 (hot rolling size, shape, weight and allowable tolerances); JISG3192-94(hot rolled steel shape, size, weight and allowable tolerance; DIN17100-80(quality standard of common structure steel); ГОСТ535-88 (technical conditions of common carbon steel).

According to the above mentioned standard requirements, delivery of steel bundles, bundling times, each bundle length and other details should meet the stipulations. The general situation is bare delivery. Attention should be paid to moisture in both transpotation and storage.

 

Mechanical Property Test

(1) inspection method

①Tensile test method. The common standard inspection methods are GB/T228-87, JISZ2201, JISZ2241, ASTMA370, ГОСТ1497, BS18, DIN50145, etc.

②Bending test method. The common standard inspection methods areGB/T232-88, JISZ2204, JISZ2248, ASTME290, ГОСТ14019, DIN50111, etc.

(2) performance index: the inspection projects for performance testing are mainly tensile test and bending test. The indexs includes yield point, tensile strength, elongation, bending qualification, etc.
