Quick Look at the Steels Used for Fasteners
As we all know that fasteners are those hardware devices that are often used for joining or holding two or more components together as a non-permanent joint. Yes, the joins are often permanent or non-permanent and they can be easily separated without creating any damage to the joints. These fasteners are manufactured in using various types of steel, where few of these steels used for fasteners are listed in the below-given article.
Types of steels used for manufacturing fasteners:
Alloy steels- it is steel that is alloyed with the nickel, molybdenum, and chromium and is considered best for those areas where strength is required. This type of steel has a good cold forming features and properties when it is annealed and is heat-treated for the combination of toughness, strength as well a shock resistance.
Carbon steel- fully-killed, fine grain basic steel that is available with no alloying agent. The low carbon steel has carbon content from 0.06 to 0.22% and often exhibit good ductility for the cold forming. However, the medium carbon steel contains 0.50% and is stronger but it is less ductile. This steel often responds well to temper and quench.
Leaded steels- when the lead is added to steel it improved machinability. The leaded steel is identified by the letter “L” in the SAE and AISI designation. Lead is the commonly added series of the screw machine steel and it allows lead as one of the alloying agents for a certain level.
Austenitic stainless steel- this type of steel is generally non-magnetic and has excellent corrosion resistance because of a large amount of chromium and nickel content. Their cold-forming characteristics are mainly subjected to the work hardening.
Martensitic stainless steel- this type of metals are chromium steels with some or no nickel content. This type of steel is magnetic and can easily be heat treated. They even have high strength and lower corrosion resistance and are harder.
Aluminum alloys- it is not steel but is mostly used for manufacturing fasteners. They have cold-forming features and can be used when there is a requirement for secondary machining.
So, these were the few types of steels used for fasteners. However, when we are choosing ASTM A193 Stainless Steel Fasteners it is important to know its specifications and other details. So, let’s know about its specifications here:
These are stainless steel fasteners that include ASTM A193, ASTM F593, and ASME SA193 specifications and ASTM, ASME, EN, GB, BS, JIS standards. The size of these fasteners varies from M02 to M30 and length varies from 3mm to 200mm. These fasteners are available to customers in varied shapes and sizes as per their demand and requirement. Furthermore, to check the quality of these fasteners various tests are done like a hardness test, flaring test, flattening test, radiography test and more. All these tests are done under the supervision of experts and as per industrial norms. With it, they are packed in the high quality of packaging material with proper labeling.
So, this was all about the different types of steels that are used for fasteners and
