303 and 304 Stainless are probably the most commonly listed grades, the usual grade for stainless fasteners. They are corrosion-resistant and durable.

I just need to give these a magnet check, so you can see some are magnetized others aren’t. Grade 316 is the usual molybdenum-bearing grade. Stress corrosion cracking begins above about 60ºC. 316 is considered immune to potable water with as much as about 1000mg/L chlorides at ambient temperatures, decreasing to about 500mg/L at 60ºC. It has good oxidation resistance in intermittent service to 870ºC and in continuous service to 925ºC.

Grade C is a thru-hardened medium zinc plated alloy metal. No head markings (manufacturers mark may also be included). Finish is in energy to Grade 8 but with out the yellow colour. I actually have an array here of different of supplies. I wish to go through the supplies first and give them the check.

Technique For our stainless

  • Not much but there’s some partial magnetic field to that.
  • This is a 316 stainless and on this scenario there isn’t any pull from the magnet.
  • This is an 18-eight which has little or no pull, as you can see.
  • This is also, just so you understand, utilized in heavy salt-water applications corresponding to on boats.

Cold working (normally drawing) produces enhanced levels of tensile strength. However, after chilly working, some magnetic properties could also be evident. Heat Treatment is by answer annealing – Heat to °C and funky quickly. Alloy Steel is the most material that fasteners are manufactured in.

A grade eight bolt has a stronger rating with a PSI of 150,000. Grade 5 alloy metal is a medium carbon zinc plated alloy steel that is warmth handled to increase hardness. Grade 5 bolts have three evenly spaced hash marks on the top markings (manufacturers mark may also be included).

All austenitic stainless-steel fasteners are normally non-magnetic within the annealed condition. Heat Treatment is by resolution annealing – Heat to ºC and funky rapidly.


Alloy metal fasteners are often treated, coated or plated with zinc for additional corrosion resistance. Alloy steel is used for the hot dipped galvanized process, treated in a molten zinc bathtub which creates a tightly bonded alloy finish. Alloy metal is most often out there in Grade A, Grade C, Grade 2, Grade 5 and Grade eight. (11.5%-13.5% Chrome, .15% Maximum Carbon) – Since this grade of stainless-steel may be hardened up to approximately 40 Rockwell C, it’s durable in most environments. (sixteen%-18% Chrome, 10%-14% Nickel, .08% Maximum Carbon, 2.00% Maximum Molybdenum) – This grade of steel is used and really helpful for applications in severe, harsh or marine environments.

We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.
