How to determine the stainless steel plate

by yane Yang Sales Manager

The surface of stainless steel plate is relatively smooth, the plasticity, toughness and mechanical strength are higher, to a certain extent, acid and alkaline gas solution or other corrosive media, is a kind of alloy steel is not easy to rust. Stainless steel plate has been widely used in chemical, food, pharmaceutical, papermaking, petroleum, atomic energy and other industrial fields, as well as civil fields such as building, kitchenware, vehicle, electrical appliance parts and so on.

Stainless steel plate

Generally speaking, stainless steel plate can withstand the corrosion of oxalic acid, sulfuric acid, ferric sulfate, nitric acid, nitric acid hydrofluoric acid, sulfuric acid copper sulfate, phosphoric acid, formic acid, acetic acid and other acids. The corrosion resistance of stainless steel mainly depends on its chemical composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the metallographic structure of steel body, the main role is chromium. Chromium has a high chemical stability, can form passive film on the steel surface, so that the metal is isolated from the outside world, protect the steel plate is not oxidized, increase the corrosion resistance of steel plate. When the passivation film is destroyed, the corrosion resistance will decrease.

The thickness of the stainless steel plate is greater than 1.2mm, and Rockwell hardness tester is used to test the hardness of HRB and HRC. Stainless steel plate with thickness of 0.2 ~ 1.2mm is tested with surface Rockwell hardness tester HRT and HRN hardness. A stainless steel plate with a thickness ratio of 0.2mm is used to test the hardness of HR30Tm by using a diamond anvil cell with a Rockwell hardness tester.

Stainless steel plate determination method can use stainless steel plate determination liquid.

Stainless steel plate determination, can quickly distinguish between 200, 201, 202, 301, 304, 316, 316L, 309, 310, 321, stainless steel is a kind of medicine, able to recognize and distinguish types of stainless steel material, identification, testing, identification, testing etc.. It is based on analytical chemistry, can make the battery power make the reaction surface, generating colored complex control technology through appropriate measuring elements and the reagent, realizing rapid determination of metal elements in stainless steel. The technology is a global leader, which plays an irreplaceable role in the field rapid determination of stainless steel materials, sorting, recycling and reuse of stainless steel scrap.

Stainless steel plate liquid products have the following characteristics: 1. The product is suitable for the determination of nickel, molybdenum, titanium and other elements in stainless steel, the accuracy is more than 95%, the cost is only 0.05 yuan per time. 2, the use of no equipment, easy to carry, anytime, anywhere can be detected. It is especially suitable for metallurgical furnace analysis and material recycling industry. 3 simple operation, as long as the liquid drops on the stainless steel, with 9V battery power reaction for 1-8 seconds. Look at the color to determine the approximate ingredients. 4, rapid reaction, only within a few seconds to know the general composition of stainless steel.

Rapid determination of Ni stainless steel plate liquid qualitative, low Ni (200), Ni2 (201), Ni4 (202), Ni6 (301), Ni8 (304), Ni14 (309, 316L), Ni20 (310), Ni40, Ni60, Mo2 (316), stainless steel, steel and other liquid identification. As long as the drop point on stainless steel, liquid and stainless steel chemical reaction immediately, through the reaction of different colors, can clearly determine the type of stainless steel. Especially, the discrimination of 202, 301, 304 and 316 is the most obvious. Each cell must be equipped with a battery, used for electrolytic water, accelerated reaction, is that you analyze the stainless steel plate of the liquid material.
