About This Product

Features
■High strength: 4 times the proof strength of SUS304 (A2-50) and 2 times that of SUS316 (A4-70)Although it is made of stainless steel, BUMAX satisfies the same strength class 10.9 as steel bolts, and is four times and twice as strong as common stainless steel bolts SUS304 (A2-50) and SUS316 (A4-70), respectively. (yield strength). BUMAX has been able to downsize the 20mm diameter bolt design of SUS304 (A2-50) to 10mm diameter, achieving a weight reduction of one-fourth.

■Corrosion resistance: No corrosion occurred even after 10 years of testing in marine environmentGuarantees overwhelming corrosion resistance that surpasses other stainless steel bolts:
- Obtained better results than SUS after 10 years of atmospheric exposure in coastal areas, and proved three times more corrosion resistant than SUS316 in a 20% sulfuric acid corrosion test.
- Guaranteed corrosion resistance for 30 years even when used on ships exposed to the sea.

■Heat resistance: Maximum operating temperature in the atmosphere is 600℃BUMAX exhibits outstanding heat resistance compared to general stainless steel bolts. SUS304/SUS316 can normally be used up to 400℃, but BUMAX can be used up to 600℃, which is 50% higher. For stainless steel bolts whose strength is increased by heat treating martensitic materials, the maximum operating temperature is set at 200℃, one-third of BUMAX.

■Non-magnetic: Outstanding non-magnetic with magnetic permeability of 1.006 (BUMAX 88)One of the characteristics of stainless steel is that it is non-magnetic. The closer the magnetic permeability is to 1.000, the more non-magnetic it is. Compared to SUS304 (A2-70), which has a magnetic permeability of 1.400, BUMAX has high non-magnetic properties with a magnetic permeability of 1.006. It can be safely used in various precision electronic devices that require a non-magnetic environment.

■Seizure resistance: Friction coefficient when tightening bolts is less than 50% of SUS316The coefficient of friction is extremely low compared to general stainless steel bolts, allowing for excellent tightening workability.
