JIS G3127 SL9N590 steel is a low-alloy steel, which contains elements such as vanadium, manganese, molybdenum, chromium, and nickel. These elements give JIS G3127 steel superior strength and wear resistance, as well as its resistance to oxidation and crevice corrosion. The mechanical properties of JIS G3127 SL9N590 steel are highly dependent on the chemical composition of the steel, as well as the rolling and heat treatment process. JIS G3127 SL9N590 steel typically has a tensile strength of 490–640 MPa, an ultimate tensile strength of 590–770 MPa, Elongation of 20–42%, and a yield strength of 215–355 MPa.

JIS G3127 SL2N26 is an iron-alloyed steel containing various elements in varying amounts. It has a low carbon content that delivers a good combination of strength, cold formability and good weldability. Other elements making up the alloy are manganese, silicon, phosphorus, and sulfur – all of which play an important role in JIS G3127 SL2N26 overall properties.

JIS G3127 SL3N26 is an exceptional family of low carbon steels that provide, excellent strength-to-weight ratios, varied mechanical properties, and easy maintainability. The steel is used extensively in automotive, aerospace, and other industries where strength, corrosion resistance and machinability are important. Specific heat treatment and alloying processes can further increase the steels' versatility and mechanical characteristics, making it an attractive option for many different applications.

JIS G3127 SL5N590 has a yield strength of over 355 MPa, meaning it is capable of withstanding large loads before it deforms permanently. It also exhibits a high tensile strength of over 500 MPa and an excellent combination of yield strength and ductility, which helps to make it a suitable material for use in transportation applications, such as automotive components.

Due to the alloying and low carbon content of the JIS G3127 SL2N255s, they can be bent, cut and welded into almost any shape. This makes them excellent for use in applications that involve substantial fabrication, such as automotive frames, tools for special applications and agricultural machinery. Furthermore, when properly hardened, the steels provide greater resistance to wear and tear as well as damage from impacts and temperature changes.

JIS G3127 SL9N53 steel has a high melting point, which makes it an ideal steel for applications which require the steel to be heated for a long period of time. Its melting point is approximately 1450°C (2642°F). It has very good heat resistance, which allows it to be used for applications that require prolonged exposure to temperatures over its melting point. JIS G3127 SL9N53 steel also exhibits good thermal shock behavior, meaning that it resists sudden changes in temperature well. Additionally, it has good creep resistance, meaning it is less likely to deform or fail at high temperatures over a prolonged period of time.

Impact resistance is a measure of a material's ability to absorb the shock of impact. JIS G3127 SL3N28 steel generally has an impact resistance of around 30 to 50 J/cm2. This is lower than the impact resistance of mild steel, which is usually around 60 J/cm2. This lower impact resistance makes JIS G3127 SL3N28 steel less suitable for applications that require protection against impacts and shocks.

JIS G3127 SL3N45 is a low carbon steel that is composed of 0.40% – 0.60% carbon. It is manufactured using various techniques, including hot and cold rolling, electroplating and other production methods, and can be chosen according to the degree of mechanical properties desired. The variation in carbon content and the production methods used affect the mechanical properties of the steel, influencing its strength, hardness, ductility and ability to resist fatigue.

JIS G3127 SL3N255 is an iron-alloyed steel with a low carbon content. It contains iron, manganese, silicon, phosphorus, and sulfur – all of which work together to create a material with excellent strength and machinability, making it ideal for use in a wide range of industrial and engineering applications. Its low carbon content also provides good weldability, toughness and ductility.
