Frequently Asked Questions
SS304 stainless steel pulley blocks provide excellent corrosion resistance for most industrial and outdoor applications. They contain 18% chromium and 8% nickel, making them suitable for general marine, industrial, and hardware applications.
SS316 pulley blocks contain 16% chromium, 10% nickel, and 2% molybdenum, offering superior corrosion resistance in saltwater, chemical, and highly corrosive environments. For marine applications, coastal installations, or chemical exposure, SS316 is the recommended choice.
Yes. Stainless steel pulley blocks are highly rust resistant due to their chromium content, which forms a protective oxide layer on the surface. Both SS304 and SS316 grades provide excellent protection against rust and corrosion.
However, they are not completely rust-proof. Prolonged exposure to harsh chemicals, salt spray without cleaning, or oxygen-deprived environments can cause surface corrosion. Regular maintenance and cleaning will ensure maximum service life.
Absolutely. As an OEM pulley block manufacturer, we specialize in custom manufacturing according to your drawings, samples, and technical specifications. We can produce custom sizes, special materials, unique wheel structures, and private label packaging.
