What is the mill test certificate?
A Mill Test Certificate (MTC), or Mill Test Report (MTR), is issued by a manufacturer to certify the chemical and mechanical features of a product and its compliance to the applicable norms and technical specifications.
What is the minimum yield strength of steel?
8.6.1 Steel piles Steel pipe piles should have a minimum yield strength not less than 35,000 psi. Structural steel piles should conform to ASTM A36, ASTM A572, and ASTM A588.
What is meant by 3.2 certification?
EN 10204-3.2 type quality certificate. EN 10204 3.2 certificate is the most restrict standard level for the steel pipe products.It indicates the certification shall be additional countersigned and verified by independent related all the tests, 3.2 certificate cost higher than 3.1.
What metal has the highest yield strength?
1. Carbon Steel
- It has a Yield Strength of 260 Mega Pascals.
- Tensile Strength of 580 Moa.
- Around 6 on the Mohs scale.
- Is highly impact resistant.
Do you need Cert for 55 ksi Yield?
They should be able to provide the actual certs for the heats they use, since they do track that info. It a material barely tests to 55 ksi yield, you might hesitate to design for 55, but if it tests to 58 or 60, you might be more willing to accept that the lower bound would exceed 55.
Can a mill certificate be used for design strength?
But, the design strengths are still limited to the higher ASTM designation properties, not the certificate properties. The purpose of mill certifications is to verify that the material performs within the RANGE required by ASTM. In nearly all cases, I would avoid using mill certificates for design properties.
Do you design for the minimum yield strength?
(Doing this might also affect weld qualification tests, etc.) If you buy a piece of steel, then design for the as-tested yield strength instead of the minimum-specified yield strength, that’s a little different; you are simply eroding the factor of safety that the design codes have incorporated, and this is generally not the intent of the codes.
Is it acceptable to exceed the ASTM yield strength?
There is nothing magic about the ASTM yield strength, and it is not tied to anything except the minimum values the mills involved in writing the spec can consistently achieve. It should be acceptable to have and use a yield strength which exceeds the ASTM nominal strength.
