The code is comprised of two numbers separated by a dot. This dot is not a decimal marker but is merely a means of separating the two parts of the code. The number to the left of the dot when multiplied by 100 provides an indication of the ULTIMATE STRENGTH in Mega Pascals while the number to the right when multiplied by 10 times the preceeding number gives YIELD STRENGTH (Mega Pascals - MPa) or STRESS at 0,2% PERMANENT SET (MPa) depending on the strength grade; e.g. 8.8 Ultimate Strength: 8 x 100 = 800 MPa Yield Strength or Stress at 0,2% Permanent Set: 8 x 8 x 10 = 640 MPa How are they made?

Is carbon steel and high tensile steel the same?
No, carbon steel and high tensile steel are not the same. Carbon steel is a type of steel where the primary alloying element is carbon, and it can have varying carbon content, affecting its hardness and strength. High tensile steel, on the other hand, is specifically designed to have high strength and tensile properties, often achieved through alloying elements like manganese, nickel, or chromium, and specific heat treatments. While high tensile steel can be a type of carbon steel, not all carbon steels are classified as high tensile steel.
What tensile strength bolts should i use for leaf springs?
For leaf springs, it's essential to use bolts with a tensile strength of at least 120,000 psi, typically made from high-strength materials like grade 8 steel or alloy steel. These bolts are designed to endure the significant loads and stresses experienced in suspension systems. Additionally, consider using bolts that are specifically rated for automotive applications to ensure reliability and safety. Always check manufacturer specifications for the exact requirements related to your specific vehicle or application.
What is the different between stud bolts and hex bolts?
Typically, a stud bolt refers to an un-headed fastener, like a piece of all thread rod. A hex bolt is common a six-sided fastener, available in many grades.
What is the tensile strength of hardox 400 steel?
Hardox 400 steel typically has a tensile strength of around 1,200 MPa (megapascals). This high tensile strength, combined with its excellent toughness and abrasion resistance, makes Hardox 400 suitable for demanding applications in industries like construction and mining. Its unique properties enable it to withstand heavy wear while maintaining structural integrity.
What are the 3 grades of steel?
The strength of steel is graded based on it's yield strength- the point that it will have a permenant deformation from a load. Steel will be graded however an engineer requires it to be in order to meet the design criteria. In order to keeps things simple and economical, common grades are: Mild which is essentially untreated for any design strength; A36 (with a 36,000 psi yield strength); and A51 (with a 51,000 psi yield strength). Most buildings are designed with A36 in mind and it is by far the most common. Cars, industrial equiment, and special construction may use A51 or higher. Since steel becomes more expensive the more it is treated, any product or assembly requiring anything other than standard yield strength will require an analysis showing the cost savings of using less higher-strength steel versus more lower-strenght steel. Steel comes in other varieties, like stainless (with its own grading characteristics) or corten (meant to be exposed to the weather).
What grade are strut bolts?
Strut bolts are typically made from high-strength steel and can vary in grade depending on the manufacturer and specific application. Common grades for strut bolts include Grade 8 (as per the SAE standard) or equivalent metric grades like 10.9 or 12.9. The grade indicates the tensile strength and hardness of the bolt, which is crucial for ensuring safety and durability in suspension systems. Always refer to the vehicle's specifications for the appropriate grade when replacing strut bolts.
How many grade of bolt?
Bolts are typically classified into several grades based on their strength and material properties. Common grading systems include the American Society for Testing and Materials (ASTM) grades, such as ASTM A307, A325, and A490, as well as the SAE grades, like Grade 2, Grade 5, and Grade 8. Additionally, metric bolts are graded according to ISO standards, such as 8.8, 10.9, and 12.9. Each grade indicates the bolt's tensile strength and suitability for different applications.
Is carbon steel and high tensile steel the same?

Carbon steel is a type of steel where the primary alloying element is carbon, and it can have varying carbon content, affecting its hardness and strength.

What is the tensile strength of mild steel?
Mild steel is a fairly general classification and can cover a considerable variation in material properties. Cold drawn grades in particular will have a higher tensile strength than hot rolled. Something like 400 MPa for yield stress and 500 MPa for ultimate tensile strength is quite common.
Which metals are not strong in tension?
Metals that are typically not strong in tension include lead and tin. These metals have relatively low tensile strength and are more malleable, making them prone to deformation under tensile loads. Additionally, some alloyed metals, like certain grades of aluminum and zinc, may also exhibit reduced tensile strength depending on their composition and processing.
What raw material used for 12.9 grade?
The raw material commonly used for manufacturing 12.9 grade fasteners is alloy steel, specifically a high-strength carbon steel like SCM435 or similar grades. These steels typically contain elements such as chromium and molybdenum, which enhance their mechanical properties, including tensile strength and hardness. The 12.9 grade indicates a minimum tensile strength of 1,220 MPa (megapascals) and is often used in applications requiring high strength and durability.
The tinsel strength like a grade 8 exhaust manifold bolt is grade 8 which has 5tics on the head what about metric?
It's TENSILE strength and on metric bolts it is indicated by a number.
What is Mexico's grade levels?
Like many jurisdictions in the United States, Mexico has primary school, junior high school, and high school. Students go to primary school for grades 1 to 6, junior high for grades 7 to 9, and high school for grades 10 to 12.
What grades do you need for getting into dentistry for university like i mean what grades do you need in like high school?
In high school, you need very good grades to get into a good college or dentistry to be more exact. yeah that is true but to be more exact you need 5 As in gcse. and if i was you i would make sure i have them in maths English and science.
Do gummy worms have a high tensile strength?
Oh, dude, gummy worms are not exactly known for their strength. I mean, they're more like squishy little guys than tough cookies. So, if you're planning on using them in a tug-of-war competition, you might want to reconsider your strategy.
What is the tensile strength of diamond and how does it compare to other materials?
The tensile strength of diamond is very high, around 60-100 GPa. This makes it one of the strongest materials known, surpassing most other materials like steel and even carbon fiber.
