If you want to get the S45C steel price, please do not hesitate to contact us. Any need in S45C Chemical Composition and Mechanical Properties, please feel. JIS Steel S45C is excelling in weldability & machinability, and S45C steels can be subjected to various heat treatments. There are some other structural steel standards and steel grades similar and equivalent to JIS S45C Steel Grade, as shown below: DIN C45, CK45, AISI Temper immediately while still hand to oC hold s45c material properties until temperature is uniform throughout the section soak minutes air ress RelievingHeat.

European standard steel grades[ edit ] EN steel grade designation system.
So S has a minimum yield strength of MPa for the s45c material specification thickness range covered by the relevant standard — i. One is to place importance on the strength of the weld metal and adopt such a welding consumable that produces the weld metal whose strength is similar to that of the base metal.
JIS S45C Steel, Normalized
The other is to place more importance on the crack resistance of the weld metal than on its strength. Generally speaking, when other conditions are the same, the crack resistance of a weld joint becomes better as the strength of the weld metal becomes lower. Therefore it is necessary to pre-treat material surfaces by cleaning them and adjust the atmosphere of the furnace s45c material specification heat treatment.
RX gas is used as a standard furnace atmosphere during quenching, NX gas during tempering, but N2, H2, AX gases, s45c material specification others are also used. In some cases, neutral salt-bath furnaces, metal bath furnaces, furnace tubes, cases, and other equipment is used to ensure that the s45c material specification does not come into direct contact with the air.
Quenching In most cases, a value around the midpoint of the quenching temperature range in the table above is used as the quenching temperature.
This temperature is maintained for anywhere from several tens of seconds to several minutes depending on the material grade, dimensions, shape, required properties, and quenching method. Quenching conditions have a significant influence on the properties of the product.
If the quenching temperature is too high or is maintained for s45c material specification long, grains become larger, toughness is reduced, and the risk of decarburization increases.
Of course, the weld HAZ can be hardened even if austenitic stainless steel welding consumables s45c material specification used. But absence of diffusible hydrogen in the weld metal is considered to contribute to crack resistance together with stable structure of the weld metal.
Hence, s45c material specification it is impossible to apply preheating or where there is no problem of thermal fatigue due to difference of thermal expansion coefficient, austenitic stainless steel welding consumables may be used.
