The manufacturer of manganese steel screen reminds you how to distinguish the good from the bad

Discrimination Method of Manganese Steel Screen Mesh
Everyone wants to buy high-quality and low-cost high-quality manganese steel screen, but it is difficult to distinguish by naked eyes. It is very distressing to get the identification results only after ten and a half days of testing by the appraisal agency. Is there a quick method to distinguish the advantages and disadvantages of the manganese steel screen? Zhongxu Screen Co., Ltd. will offer you advice.
1. Magnet Detection Method
Since the implementation of this year's strongest environmental protection system, the cost of enterprises has increased, profits have decreased, and screening customers continue to press low prices on manganese steel screens. Some manufacturers of manganese steel screens have to use raw materials of manganese steel wires to replace high manganese steel with silicon manganese steel and ordinary steel. In fact, these steels are not very different in nature, but only some trace elements have been added to the steel. 。 These materials are easy to rust after damp screen, so manganese steel screen manufacturers have done rust-proof treatment before leaving the factory, one screen surface sprayed with anti-rust paint; the second screen surface sprayed with grease, so it is difficult for screening enterprises to distinguish after treatment.
Magnets are the simplest way to distinguish high manganese steel, ordinary steel and manganese steel screen. Some manganese steel can be attracted by magnets. For example, the manganese steel sieve mesh made of 65Mn material has great suction; the manganese steel sieve mesh made of M13 material has very weak suction; while the manganese steel sieve mesh made of high manganese steel is a mixture of alloys, each material in the mixture maintains its original properties, and there is iron in high manganese steel, so it can be magnetized, but it has no magnetism, even if magnetized, its magnetism is much lower than that of other steel material sieve mesh.
2. Chemical detection
This chemical detection method has some limitations. It is limited to the detection of high manganese steel screen material. Before the detection, the rust-proof paint or grease on the surface of high manganese steel screen is removed. Copper sulfate solution is dripped on the fault and wiped off with a clean cloth. If the surface becomes red and non-magnetic after the wiping, it is high manganese steel, and the common steel or low-alloy steel that becomes red and magnetic.
3. Physical Detection Method
The main function of manganese is to improve hardenability. For use, high content, better strength and hardness, and lower toughness, high manganese steel screen mesh is easy to break. The higher the proportion of manganese, the easier the screen wire to break.
The above method is only a general detection method, the accuracy is not necessarily very high, but it can be used as a preliminary detection method, more accurate measurement needs special detection agencies to do spectral analysis to determine.
