No. It is 17 Mpa LESS strong 60 Mpa = 60 N/mm2
1 MPa = 10 kg/cm2 (MPa is pressure, kg/cm2 is mass/area not actual pressure)
3000psi = 20.67MPa
Mega Pascal - measurement of pressure
1 MPa = 1000000 N/m2 and 1 N = 1 kg*m/s2
Tensile Strength is 570 MPa (i.e. 82.7 ksi) - (Ref. API 5L - Specification for line pipe - Forty Forth Edition Section 9.3.2- Table 6)
42 mpa for pre tension and 35 mpa for post tensioned
33 Mpa...for 43 grade cement
10.9 grade steel is a common type of high strength structural steel that is typically used in construction and manufacturing applications. The "10.9" refers to the minimum tensile strength in MPa, which is 1000 MPa for the 10 part and 900 MPa for the 9 part, making it a strong and durable material for various purposes.
Grade 60 refers to the yield strength of steel reinforcement, indicating it can withstand 60,000 pounds per square inch of stress before deformation. On the other hand, 60 MPa specifies the material's compressive strength in megapascals, showing how much pressure it can resist before breaking. While Grade 60 is a measure of tensile strength, 60 MPa is a measure of compressive strength.
The "metric grade" your asking about conforms to North American metric standards. The 12.9 should have a ultimate tensile strength of 1200 MPa and tensile yield strength of 1080 MPa. The 10.9 should be weaker have a ultimate tensile strength of 1000 MPa and tensile yield strength of 900 MPa. You are asking "can" it be more brittle. It should not be but it can be if a problem with manufacturer quality control.
The grade in cement mainly defile the average compressive strength after 28 days in mega pascals (Mpa) of at least three mortar cubes (area of face 50 cm squared) composed of one part cement, 3 parts of standard s and (conforming to IS 650:1966) by mass and P/4 (P is the percentage of water required to produce a paste of standard consistency as per IS standard) + 3 percentage (of combined mass of cement plus sand) of water, prepared, stored and tested in the manner described in methods of physical test for hydraulic cement. 721 hr not < 23 MPa for 43 grade, 27 MPa for 53 grade 1682 hrs not <33MPa for 43 grade, 37MPa for 53 grade 6724 hrs not <43MPa for 43 grade, 53 MPa for 53 grade
Proportions for different grades: Cement : Sand : Gravel 1 : 2 : 5 for grade C15(general purpose concrete) 15 mpa 1 : 2 : 4 for grade C25(strong) 25 mpa 1 : 2 : 3 for grade C30(very strong) 30 mpa Remember the proportion is done in terms of volume. This means the above proportions are correct if using the same measure.
EN10025 S355J2+N structural steel has the higher Tensile of 510 MPa to 680 MPa and a Yield of 355 MPa, depending upon the structural steel thickness. ensteelstandardcom/FAQ/en10025-s355j2+n-structural-steel-plate-supplier.html
