Current Condition and Problems of China's Fastener Steel
So far there are around 40 thousand items and millions of types of fasteners, and they are applied in various conditions such as high temperature, high pressure, low temperature, vibration, corrosion, over-load, alternating stress, shear resistance, and anti-torsion. However, fastener failure can very possibly trigger accidents; therefore, many China fastener companies receive clients' claim for compensation due to product quality issues. Indeed, such issues can result from unqualified materials. Hence, choosing the correct fastener material becomes a growing concern for the fastener industry.
Speaking of the condition and problems of China's Aluminum profile accessories and fastener steel, CMCA consultant states, "Although China is a major fastener manufacturing nation as well as the largest steel manufacturing nation, it started slower than other countries in the field of fastener steel development and production. The speculations of cold-forged steel are comparatively less and cannot satisfy the current demand of domestic fatsener production and export. The production and distribution of cold-forged steel even utilizes JIS steel grades like G3506, G3507, G4105, and many steel grades in ASTM."
