Do F1554 anchor bolts come in stainless steel?
The answer to this question is no. As stated in Section 1.1, the F1554 specification covers various configurations of, “…carbon, carbon boron, alloy, or high-strength alloy steel anchor bolts.” In general terms, for a steel to be considered “stainless” it must contain at least 10.5% chromium as part of its chemical composition and will often have nickel or molybdenum as additional alloying elements. The F1554 specification covers three different grades of material, Grade 36, Grade 55, and Grade 105. As you can see in the chart below of the required chemical properties for each grade within the F1554 specification, there is no requirement for chromium (or nickel or molybdenum) in any of the grades covered by the specification.
Chemical Properties of ASTM F1554
| Element | Grade 36 | Grades 55 and 105 | ||
|---|---|---|---|---|
| Sizes up to 3/4 | Sizes over 3/4 to 1-1/2 | Sizes over 1-1/2 to 4 | ||
| Carbon (max) | 0.26% | 0.27% | 0.28% | |
| Manganese | * | 0.60 - 0.90% | 0.60 - 0.90% | |
| Phosphorus, max | 0.04% | 0.04% | 0.04% | 0.040% |
| Sulfur, max | 0.05% | 0.05% | 0.05% | 0.050% |
| Copper, min (when specified) | 0.20% | 0.20% | 0.20% | 0.20% |
| * Optional with the manufacturer but shall be compatible with weldable steel | ||||
If anchors bolts need to be stainless steel then they should be specified under one of the ASTM specifications that cover stainless steel fasteners such as A193, A320, or F593. More information on the differences between stainless steel bolts made under the aforementioned three specifications can be found here.
Portland Bolt can manufacture anchor bolts as straight rods, bent bolts, and headed bolts from both Type 304 and Type 316 stainless steel. If you would like a quote on stainless steel anchor bolts, you can submit a quote request through our website right now!
Are Stainless ” L ” grade Nuts required on Stainless ” L ” grade Rods ?
@Greg- Because 316L/304L is not a fastener standard, there is no published requirement for nuts used with these steel grades. That said, if the application requires the ‘L’ grade of steel, it would make sense that both components would match.
Can I ask for quote of the following:
10 each – 316 SSL BOLT AND NUT (ANCHOR ROD) 2 1/4″ DIA. X 52″ LONG
90 each – 316 SSL BOLT AND NUT (ANCHOR ROD) 2″ DIA. X 52″ LONG
Thank you
@Ariel- One of our salespeople will contact you shortly.
Can you please supply a torque value for 1 1/4″ F1554 grade SS KSI anchor bolt.
@Ken- Anchor bolts are not normally torqued to any specific amount, but are usually just snug tightened per AISC guidelines. If a specific torque or tension is required, it should be specified by the project engineer.
Need quote on 316 grade st st anchor bolts 3/8 x 5″ FH qty 100/500/1000
@Juan- I am sorry, but we cannot manufacture anything that small. 1/2″ is our smallest diameter.
what is the grade of steel used for making anchor bolts under specification ASTM A307 A?
@Mahipal- A307A is a general purpose grade and not usually used for anchor bolts. Anchor bolts used to be manufactured per A307C, but that has been withdrawn and replaced with F1554g36. Any low carbon steel can be used for A307A, provided it meets the requirements of table 1 in A307.
