What are the different grades of carbon steel?
Below are the properties of the grades of carbon steel:
- Low Carbon Steel: Composition of 0.05%-0.25% carbon and up to 0.4% manganese.
- Medium Carbon Steel: Composition of 0.29%-0.54% carbon, with 0.60%-1.65% manganese.
- High Carbon Steel: Composition of 0.55%-0.95% carbon, with 0.30%-0.90% manganese.
What are the different grades of pipe?

How do you know the grade of steel?
The AISI/SAE numbering system uses a 4-digit number for classification. The first two numbers indicate the steel type and alloying element concentration, and the last two numbers indicate carbon concentration. For example, SAE 5130 describes a steel containing 1% Chromium and 0.30% Carbon.
What is the difference between a grade and B grade steel?
ASTM A106 Grade A: Maximum Carbon element 0.25%, Mn 0.27-0.93%. Minimum tensile strength 48000 Psi or 330 Mpa, yield strength 30000 Psi or 205 Mpa. A106 Grade B: Maximum C below 0.30%, Mn 0.29-1.06%. Minimum tensile strength 60000 Psi or 415 Mpa, yield strength 35000 Psi or 240 Mpa.
What grade is black pipe?
Black iron pipe is actually made of a low-grade “mild steel” compound. This gives it much better corrosion resistance than traditional cast iron piping. There are few standards that all black iron pipes adhere to. However, they are all made to handle natural and propane gas, which usually stay below 60psi.
What grade of steel is pipe?
ERW Standard and Line Pipe Grades
| Grade A Carbon Steel | (ASTM A53, A523, API 5L PSL1 ) |
|---|---|
| Minimum Yield Strength: | 30,000 psi |
| Maximum Yield Strength: | None |
| Minimum Tensile Strength: | 48,000 psi |
| Notes: This grade may be used for standard pipe, line pipe, or conduit pipeas specified in the various ASTM and API specifications. |
