Medical steel
Steel is a common ferrous material. The inclusion of alloying materials in the composition makes it possible to obtain a material with the desired properties. The invention of "stainless steel" led many industries to use it, this alloy became an indispensable tool in medicine and everyday life.
Properties of medical steel
The cleanliness of the device depends on whether there are microscopic cracks and scratches on it, into which dirt and harmful microorganisms can penetrate. Tools made of medical steel are very sterile, their composition does not allow bacteria to enter the structure.
The main property of medical steel is hardness. The ultra-thin blade is made only from an extremely hard alloy. Under increased mechanical load, the tool should not bend, and cracks should not form when falling, hitting a hard surface. The hardness depends on the carbon content, which should be 0.4-1.2%.
Silicon (1%), manganese (1%) are introduced into the alloy, which give elasticity to the final products.
Medical steel is very strong, wear resistant, and guarantees a long service life.
The porosity of the metal plays an important role in instrument disinfection. If it is made of a highly porous alloy, the cavities between the metal grains allow bacteria to enter, a potential spreader of infection throughout the human body. Disinfectants cannot adequately neutralize infected pores. Therefore, surgical steel is made of a low-porosity alloy that can be easily disinfected.
In addition, tools made of medical steel have the following properties:
* water resistance;
* corrosion resistance;
* inertness towards organic tissues;
* does not release toxins;
* easy to clean;
* tolerates high temperature, acid effect.
During processing, chemical reactions with inorganic substances do not take place in the alloy. And another plus - medical steel does not cause allergies.
With many advantages, medical steel is used in various fields of human activity.
Medical surgical instruments: forceps, scalpels, clamps have long been included in the daily routine of a doctor of any specialty. Prostheses that come into contact with living tissue are durable and reliable. A thin needle for a syringe and high-tech devices for complex operations have one thing in common - they are made of medical steel.
Non-toxic surgical steel is used in the food industry. Cutlery looks neat and aesthetically pleasing. Some parts of kitchen electrical appliances are cast from medical alloys.
Mechanical engineering uses medical grade steel to produce high-strength load-bearing parts. Insensitive acetic and lactic acids give the elements resistance to wear and abrasion.
Recently, medical steel has firmly occupied a niche in cosmetology, jewelry market. Jewelry wins fans because of its low maintenance and relatively low price. Attractive and physical properties: Medical steel jewelry does not scratch as much as gold and does not tarnish from moisture like silver.
65x13 steel is used in the production of knives, which is also classified as medical steel. Maintenance of such a knife does not require any special conditions.
Medical steel rolling inspection
Despite the fact that the description of medical steel shows that it is maintenance-free, there are still some rules that must be followed in order for the products to last longer. Medical instruments, also used in cosmetology, must be protected from causing infection. They must be stored in separate packages or special boxes.
Jewelry also requires attention: it is preferable to store each product in a separate container (bag, box); Clean with a polishing cloth 1-2 times a week, removing traces of grease and dirt; gold-plated medical steel jewelry should be worn separately from other jewelry to avoid minor scratches.
