    Product details

    Product Introduction

    The screw grade classification is:

    First, the bolt performance grade, that is, the performance grade of bolts for steel structure connection, divided into more than 10 grades of 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, 12.9. The bolts for steel structure connection are classified into more than 10 grades of 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, etc., of which the bolts of grade 8.8 and above are made of low carbon alloy steel or medium carbon steel and heat treated. (Quenching, tempering), collectively referred to as high-strength bolts, the rest are collectively referred to as ordinary bolts. The bolt performance grade label is composed of two parts, which represent the nominal tensile strength value and the yield ratio of the bolt material.

    Second, the steel structure connection bolt performance grade is divided into 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 and other more than 10 grades, of which 8.8 grade and above bolts are low carbon alloy steel or medium carbon steel and After heat treatment (quenching, tempering), commonly known as high-strength bolts, the rest are commonly referred to as ordinary bolts. The bolt performance grade label is composed of two parts, which represent the nominal tensile strength value and the yield ratio of the bolt material. For example: a bolt with a performance class of 4.6, which means:

    1. The nominal tensile strength of bolt material is up to 400MPa.

    2. The yield ratio of the bolt material is 0.6.

    3. The nominal yield strength of bolt material is up to 400×0.6=240MPa

    Performance grade 10.9 high strength bolts, after heat treatment, can achieve:

    1. The nominal tensile strength of bolt material is up to 1000MPa.

    2. The yield ratio of the bolt material is 0.9.

    3. The nominal yield strength of the bolt material is 1000×0.9=900MPa.

    Product Advantages

    Stainless steel screws, as the name suggests, must be made of stainless steel screws and wire rods. The performance of stainless steel screws is mostly related to stainless steel. Consider the performance and organization of stainless steel, and understand the performance of stainless steel. Therefore, it is understood that stainless steel has good mechanical properties such as rust resistance, corrosion resistance, high temperature resistance, etc., and stainless steel screws certainly have these good mechanical properties. As stainless steel materials become more and more excellent. The mechanical properties of stainless steel screws produced by the screw industry are getting better and better. Anti-rust, anti-corrosion ability, and high temperature and high pressure is getting stronger.


    Product Application Scenario

    Stainless steel screws are widely used in machinery, petrochemical, telecommunications, chemical, construction, power, textile, sports equipment, paper, sewage, shipbuilding, automotive and other industries. With the improvement of domestic economic living standards, the application range of stainless steel screws will be more widely.

    Mainly used for: environmental protection equipment, medical equipment, communication equipment, power facilities, electronic products, instrumentation, food machinery, petrochemical, ship assembly, pump and valve pipelines, building curtain walls, outdoor venues, sports facilities, outdoor decoration, etc.
