HS Code 73181535 – Screws, bolts, stainless.
What is ASTM F593?
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.
Is standard for SS bolts?
304 stainless steel is one of the most widely and commonly used stainless steel grades. It is also known as the 18 – 8 chromium nickel grade by the SS 304 Nut Bolt Manufacturer.
|Stainless Steel 304 Fasteners Specifications||ASTM A193 / A193, ASME SA193 / SA194|
|304 Stainless Steel Fasteners Length||3 mm to 200 mm|
What class are stainless steel bolts?
18-8 Stainless Steel:
303 and 304 Stainless are the most commonly listed grades, the standard grade for stainless fasteners. They are corrosion-resistant and durable. They are often used in marine applications in freshwater environments but will not work as effectively in a salt-water environment as 316 stainless.
What grade of bolt is stainless?
Stainless commonly comes in grades 18.8 (304) or T316. Stainless steel bolts are rated for corrosion resistance. Bolt strength is rated in PSI (pounds per square inch). A stainless steel bolt has the same PSI rating as a grade 5 bolt (125,000 PSI).
What is ASTM for stainless steel?
ASTM International Standard A484 is the standard specification for stainless steel bars, billets, and forgings. The spec covers wrought stainless steel bars, shapes, forgings, and billets or other semi-finished materials, excluding wire, for forging.
What grade bolt is F593C?

Is steel a code for screws?
HSN Code 7318: Screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter pins, washers, incl. spring washers, and similar articles, of iron or steel (excluding lag screws, stoppers, plugs and the like, threaded) Products Include: Logitech Webcam.
Is Bolt a specification 1367?
The IS 1367 Grade 8.8 specification covers carbon steel bolts and studs ranging from M-6 to M-39 diameter. We use high carbon steel material and high alloy steel raw materials to achieve the required properties in this standard.
Is A193 stainless steel?
ASTM A193 Grade B6 bolts and threaded rods are manufactured from AISI 410 stainless steel which has been quenched and tempered to increase strength. Because these bolts are manufactured from stainless steel, they are used in highly corrosive environments with elevated ambient temperatures.
How can I tell if a bolt is stainless steel?
Stainless steel, in most cases, is non-magnetic. With bolts, stainless steel can be identified by the head marking. These markings indicate steel grade and tensile strength. When installed, stainless steel screws and bolts are known for their longevity.
What grade is a bolt 304 stainless steel?
18-8 stainless steel, also sometimes called 304 stainless, is the most common type used for fasteners such as machine screws and nuts. It contains 18% chromium and 8% nickel and features strong corrosion resistance, but is softer, and thus weaker, than some other grades such as 410 stainless.
What are bolt grades?
There are several grades of bolts but the three common grades for SAE are 2, 5 and 8. The common class (grades) for metric are 5.8, 8.8, 10.9 and 12.9. Each grade has a specific bolt strength. No matter the system used to grade the bolts, the higher number means the stronger the bolt.
Is a stainless steel bolt as strong as a steel bolt?
It is a common misconception that stainless steel is stronger than regular steel. … Therefore, when compared to regular steel, the stainless alloys used in bolts are slightly stronger than an un-hardened (grade 2) steel but significantly weaker than hardened steel fasteners.
How do you tell the grade of a bolt?
You can usually figure out the grade, or strength, of a bolt by looking at the markings on its head. English bolts (U.S.S. or S.A.E) are categorized by grade, from grade 2 to grade 8, where the grade represents inch strength. The higher the grade, the stronger the bolt.
Can you get 8.8 stainless steel bolts?
A grade 8.8 fastener can be manufactured from any material whose mechanical properties meet or exceed the requirements set forth in the relevant harmonised standards.
