Alexandria sheet, tool steel U8A, HVG, 9XC, 5HNM, R6M5, spring-spring 65G

5g - spring structural steel. Steel alloyed with manganese.
This is cheap knife steel. It is used for the manufacture of paper knives, throwing knives, knives of earthmoving machines (cultivators, bulldozers, graders, etc.). For kitchen knives, 65g is used very rarely. The cutting properties of this steel are good. In addition to knives, springs, springs, friction discs, gears, flanges, thrust washers and many other wear-resistant parts that work without shock loads are made from 65g. Steel 65 g is not used for welding structures. Contact spot welding is allowed.
The corrosion resistance of 65g is low.
It is processed by cutting and forging quite well.
Steel can replace 65g: 60s2a, 55s2, steel 70, u8a, 9khs, hvg, 50khfa. Sheet steel for special purposes is a widely used material in mechanical engineering, construction and economic activities. Due to its high chemical resistance and purity, food-grade special steel is in demand in the food industry.
Special steels are high-alloy steels and alloys according to GOST 5632, characterized by high corrosion resistance and an increased temperature limit.These steels have earned their name due to the presence of certain chemical, physical and mechanical properties, which are provided by special alloying impurities and technological processing.
Modern special steel is a product with unique properties, which are obtained by introducing metallic and non-metallic elements into the iron melt. The resulting structural bonds give steel special qualities.
The improvement in the quality of special-purpose steel is influenced both by the master alloys used and the procedure for pre-cleaning from unwanted impurities. Spring steel is a low alloy, medium or high carbon steel with a very high yield strength. This allows spring steel products to return to their original shape despite significant bending and twisting.
Most spring steels (like those used in automobiles) are hardened and tempered to 45 on the Rockwell C scale. Silicon is a key component of most spring steel alloys. In the US, the most commonly used spring steel is ASTM A228 (0.80-0.95% carbon), which is also known as "music wire" or "piano wire". The main grades of spring steel are grades 60G, 65G and others, with a carbon content of 0.5-0.9%. It is used for the manufacture of springs and similar products, for example, torsion bars and springs. Because of its resistance to breakage and cracking, spring steel is also widely used in the manufacture of metal swords for stage combat. Spring steel is one of the most popular pick materials [source not given 275 days] due to its elasticity and flexibility. Also used for piano strings and spring collars. Steel for the manufacture of springs must have high elasticity and strength, this is achieved by using a high-carbon alloy alloyed with elements such as manganese, silicon, vanadium, nickel, chromium and others. These additives serve to increase the yield strength and strength of the metal. If there is a need for the resistance of the product to an aggressive environment, the chromium content can be increased up to 18%, and nickel up to 10%. Also for this purpose, tin-zinc, silicon-manganese or beryllium bronzes can be added. The most commonly used steel is AISI 301 - stainless, non-magnetic, high-strength chromium-nickel steel. It is very similar to the AISI 304 brand, differs from it in a lower nickel content - 6-7%. Recommended for use in wide-profile products that are used in mildly aggressive and atmospheric conditions. It has high ductility, good workability and excellent corrosion resistance.
Compared to the 304th and 321st grades, the tensile strength of AISI 301 steel is 20-30% higher.
