Which one has higher strength, stainless steel bolts or high-strength bolts
Under normal conditions, high-strength bolts have high strength,
The strength of stainless steel bolts generally does not exceed 800MPa.
High strength bolts are high-strength bolts that belong to a standard component. In general, high-strength bolts can withstand greater loads than ordinary bolts of the same specification.
difference
In general, high-strength bolts can withstand greater loads than ordinary bolts of the same specification.
The material of ordinary bolts is Q235 (i.e. A3) manufactured.
The material for high-strength bolts is 45 # steel, alloy steel (such as 20MnTiB, 35VB), or other excellent materials, which undergo heat treatment after production to improve strength.
The difference between the two is the strength of the materials.
One point: From the perspective of raw materials:
High strength bolts are made of high-strength materials. The screws, nuts, and washers of high-strength bolts are all made of high-strength steel, commonly used in 45 steel, 40 boron steel, and 20 manganese titanium boron steel. Ordinary bolts are commonly made of Q235 steel.
Two points: From the perspective of strength level:
High strength bolts are becoming increasingly widely used. There are two commonly used strength levels, 8.8 and 10.9, with 10.9 being the most common. The strength grade of ordinary bolts is generally lower, at 4.4, 4.8, and 5.6 levels. (8.8S and 10.9S are dedicated to steel structures)
