Products Description
The mechanical properties of Q235B steel in China are similar to those of SS400 steel in Japan. JIS Steel grade SS400 is basically equivalent to Q235B steel in China, but there are some differences in specific indicators. Steel grade SS400 equivalent Q235B requires the content of C, Si, Mn, S, P and other elements, but steel grade SS400 only requires S, P less than 0.050. Let us check Steel grade SS400 equivalent Q235B and SS400 steel differences below:
Steel grade SS400 equivalent Q235B chemical composition:
| GRADE | C | Mn | P | S | Si |
| Q235B | 0.12-0.20 | 0.30-0.70 | ≦0.045 | ≦0.045 | ≦0.30 |
| SS400 | - | - | ≦0.050 | ≦0.050 | - |
Steel grade SS400 equivalent Q235B mechnical properties:
| GRADE | YIELD STRENGTH | TENSILE STRENGTH | EXTENSION |
| MPA | MPA | % | |
| Q235B | ≧235 | 375~460 | ≧21 |
| SS400 | ≧205 | 400~510 | ≧17 |
The yield point of steel grade SS400 equivalent Q235B is greater than 235 MPa, while steel grade SS400 yield point is 205MPa. SS400 steel means steel with tensile strength greater than 400 MPa for general structure. Steel grade SS400 equivalent Q235B means ordinary carbon structural steel with yield point greater than 235MPa. The standard number of SS400 steel is JIS G3101. The standard number of steel grade SS400 equivalent Q235B is GB/T 700.
Why Steel Materials in Channels?
Steel is regarded as the best metal to use when making metal channels because of its mechanical properties.
Hardness: The capacity to tolerate surface indentation (localized plastic deformation) and scratches is referred to as hardness. Hardness can suggest scratch resistance, abrasion resistance, indentation resistance, and even shaping or localized plastic deformation resistance; therefore, it is perhaps the most poorly defined material attribute. From an engineering aspect, hardness is significant because it increases resistance to wear caused by friction or erosion caused by steam, oil, and water.
Toughness: The ability to absorb energy without cracking or rupturing. Toughness is also the ability of a substance to resist fracture when strained. The difference between toughness and hardness is that a material that deforms extensively without breaking can be called exceedingly tough but not hard.
