What is ASTM F593C?

ASTM F593 covers the chemical and mechanical requirements for stainless steel bolts, hex cap screws, and studs in diameters ranging from 1/4″ to 1-1/2″ inclusive. These fasteners are for general purpose usage and are available in seven alloy groups.

What is a F593C bolt?

The F593C marking means the bolt was made to meet an ASTM standard defining what it’s made of and how strong it will be. A superior bolt then the common hardware store bolt.

How strong is a F593C bolt?

For more frequent load-bearing applications, the bolt stamped “F593C” would be preferred. The stamp means it meets parameters set by the American Society for Testing and Materials International (www.astm.org). These bolts generally have a tensile strength that is roughly 20-percent greater than the usual 18-8 fastener.

What grade are zinc bolts?

So typically grade eight, in most cases, is coated in yellow zinc. You can see this bolt, it’s coated with a yellow zinc. These are typically, grade eights, are heated to temperatures of 800 degrees. These are very commonly used in situations where you need a very strong bolt.

What do the grades on bolts mean?

Bolts are made of different grades of steel. The grade of a bolt determines the maximum amount of stress (tensile strength) that the bolt can handle. Tensile strength is the amount of pull the bolt can withstand before breaking. The SAE marking system uses raised dashes on the bolt head to indicate strength.

What grade is stainless steel?

For example, 18/8 stainless steel is comprised of 18% chromium and 8% nickel. 304 grade stainless steel is also comprised of no more than 0.8% carbon and at least 50% iron. The chromium binds oxygen to the surface of the product to protect the iron from oxidation (rust).

What is ASTM stainless steel?

ASTM A182 F6a is a forged martensitic stainless steel with 13 wt.% chromium. Martensitic stainless steels can be high-carbon or low-carbon steel alloys. The ASTM standard A182 describes the general set of specifications about several material grades.

What is a stainless steel bolt?

Stainless Steel Bolts is basically an iron-based alloy with minimum 10.5% chromium content. The word Stainless is derived from its oxidation resistance properties thus making the steel passive to corrosion often known by the technical term corrosion resistance.
