What factors should be considered when selecting ASTM A193 B7 heavy hex cap screw?
Firstly, it is crucial to assess the specific application requirements, such as the load-bearing capacity, environmental conditions, and desired level of corrosion resistance. The material grade B7 offers high strength & excellent resistance to various corrosive environments, making it suitable for demanding applications.
Can SA 193 B7 hex cap screw be heat treated to improve their strength?
Yes, SA 193 B7 hex cap screws can be heat treated to enhance their strength properties. The heat treatment process typically involves subjecting the screws to controlled heating and cooling cycles to modify their microstructure and mechanical properties. Heat treatment can increase the hardness, tensile strength, and resistance to deformation of the screws, making them suitable for high-stress applications.
How does the size of B7 cap screws affect their price?
Generally, larger-sized cap screws require more raw material & involve additional manufacturing processes, such as machining or threading, which can contribute to higher production costs. Consequently, larger B7 cap screws tend to be priced higher compared to smaller sizes.
