FORGED STEEL FITTINGS – PIPE NIPPLES
Aluminum The benefits of aluminum fasteners are quite extensive. Aluminum has the best strength-to-weight ratio of any common metal. In addition, it weighs about one-third as much as mild steel. Because of its tendency to form a protective oxide coating upon exposure to the atmosphere, aluminum has a high resistance to normal atmospheric corrosion. This colorless oxide allows aluminum to be a great material that will not stain the item it is holding together. Another benefit is the material cost for aluminum, it is less than other non-corrosive alloys like stainless steel. In addition to not being magnetic, Aluminums high conductivity has enabled it to be used in many industrial and electrical environments.
Copper, Brass & Bronze Silicon bronze usually contains about 96 percent copper. The remainder may be silicon alone, but more often a little manganese, tin, iron, or zinc is also added. These alloys were developed originally for the chemical industry because of their exceptional resistance to corrosion in many liquids. Brass is an alloy of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. In comparison, bronze is principally an alloy of copper and tin. Despite this distinction, some types of brasses are called bronzes. The addition of tin increases the materials resistance to corrosion in marine and mildly acidic environments. Call Lightning Bolt & Supply when looking for fasteners in these alloy, such as hex bolts, nuts, washers, studs, and specials.
PH Grade Fasteners Lightning Bolt & Supply can provide fasteners in PH grades such as 13-8 MO, 17-4 PH, and 17-7 PH. This alloy is a precipitation hardened chromium-nickel-aluminum stainless steel combining high strength, moderate corrosion resistance and properties well suited for flat springs. 17-4 PH for example is used for applications requiring good strength, corrosion resistance and mechanical properties up to 800 F in service. This alloy is often used for very detailed, intricate parts due to its low distortion in heat treatment and is commonly found in a variety of springs and washers.
Stainless Steel Fasteners Stainless steel is a remarkable and versatile material with many applications. Stainless steel differs from carbon steel by the amount of chromium present. Despite many different alloys and applications, stainless steel is a very common alloy used in industrial applications. Call Lightning Bolt & Supply for stainless bolts, nuts, washers, and even specials. We also offer stainless fasteners in the following alloys: stainless steel 303, stainless steel 304, stainless steel 304B, stainless steel 304L, stainless steel 309, stainless steel 310, stainless steel 316, stainless steel 316B, stainless steel 316L, stainless steel 317, stainless steel 317LM, stainless steel 321, stainless steel 330, stainless steel 347, stainless steel 410, stainless steel 416, stainless steel 422, stainless steel 430, stainless steel 431, stainless steel 440, stainless steel 501, B8, B8M, and class 2 strain hardened.
Lightning Bolt is a premiere supplier of specialty high nickel alloy fasteners. Such alloys include: Hastelloy, Monel, Inconel, Alloy 20, Super Duplex, and many more.
COMMON ASTM GRADES
ASTM A193 Grade B7 Chromium Molybendum steel, normally AISI 4140, heat treated to 28-32Rockwell Hardness, 125,000 PSI tensile strength, 105, 000 PSI yield. It will hold it’s strength to 1000 degrees F.
ASTM A193 Grade B7M It has the same chemistry as B7. Physicals have max hardness of 235 Brinell or RC22. 100,000 PSI tensile and 80,000 PSI yield. Used in areas where H2S is present.
ASTM A193 Grade B16 Chromium, molybendum, Vanadium steel. It has the same physicals as B7. Added vanadium allows it to hold it’s strength to 1100 degrees Fahrenheit.
ASTM A193 Grade B8 18-8 Grade stainless, non magnetic, good corrosion resistance. 75,000 PSI tensile strength. Same material as AISI type 304 stainless steel.
ASTM A193 Grade B8M This is similar to B8 fasteners except with added Molybdenum. It has better corrosion resistance than B8. Hex Bolts, studs and other fasteners are common to the B8M spec.
ASTM A193 Grade B8 Class 2 Studs, bolts, and other fasteners found in this grade are considered the same as B8 except strain hardened. This is a cold working process which increases physical properties. 100,000-125,000 PSI Tensile Strength.
ASTM A193 Grade B8M Class 2 Same as B8M except strain hardened, 90,000-125,000PSI Tensile Strength.
ASTM A193 Grade BC 18-8 grade stainless with additional element of Columbium- same as type 347 type stainless steel.
ASTM A193 Grade B8T 18-8 grade of stainless with additional element of Titanium. Same as type 321 Stainless Steel.
ASTM A193 Grade B6 This has the same chemistry as AISI type 410 stainless steel, but it is heat treated. 110,000 PSI tensile strength.
ASTM A193 Grade B5 Fasteners under the B5 spec have the same chemistry as AISI type 501 SS but they are heat treated to 100,000 PSI tensile strength.
ASTM A320 Grade L7 Bolts, studs, and other fasteners under the L7 grade have the same chemical and physical properties as B7. Additional requirement that it meet a Charpy Test at 150 degrees F is needed. Such fasteners are commonly used for low temperature service.
ASTM A320 Grade B8 -18-8 Grade stainless, non magnetic, good corrosion resistance. 75,000 PSI tensile strength. Same material as AISI type 304 stainless steel.
ASTM A320 Grade B8M This is similar to B8 fasteners except with added Molybdenum. It has better corrosion resistance than B8. Hex Bolts, studs and other fasteners are common to the B8M spec.
ASTM A320 Grade B8 Class 2 Studs, bolts, and other fasteners found in this grade are considered the same as B8 except strain hardened. This is a cold working process which increases physical properties. 100,000-125,000 PSI Tensile Strength.
ASTM A320 Grade B8M Class 2 Same as B8M except strain hardened, 90,000-125,000PSI Tensile Strength.
ASTM A354 Grade BC High strength bolts for normal atmospheric temperature. 125,000 tensile. Lacks alloying elements of B7.
