  • Unique Qualities of Stainless Steel PH15-7MO
    PH15-7 grade stainless steel is categorized as a Precipitation Hardened ("PH") grade of stainless. The PH grades are used to allow fabrication in the soft, annealed condition, with subsequent hardening to the final spring temper required by part function. This material is completely unique
  • Comparative Analysis of Type 316 Stainless and 302/304, 420 Types
    Pins, stainless steel is often required for its high corrosion resistance. Coiled Spring Pins are most often manufactured from Type 302/304 and Type 420 stainless steel, but Type 316 is also available and is typically selected for its superior corrosion resistance. This paper takes a closer look at how
  • Brushless washer maker finds reliability in screwless connections
    of a stainless-steel spring, heads off the possibility of signal degradation from corrosion. The Wago blocks also reduce overall wiring and maintenance time, says PDQ electrical engineer Saul Escalante. PDQ went with blocks from Germantown, Wis.-based Wago because "We are considered the leaders
  • Frequently Asked Questions/Technical Information
    A: Different materials are better suited for different applications and environments. The Material Properties Table provides operating temperature ranges and other useful information. A: When heat-treated to spring temper, Stainless Steel becomes magnetic. Stainless Steel springs are slightly less
  • Medical Device Link .
    . Hamilton recently introduced the Softgrip Precision pipette, a liquid-transfer device that requires precise mating of a stainless-steel piston with a spring-loaded shaft, as well as a nearly zero-tolerance fit within a Teflon seal to maintain sampling accuracy and precision. Hamilton installed three

A peristaltic pump maintains sterility in handling advanced live-cell pharmaceutical and biotechnological products that cannot survive valve transition or contact with stainless steel. The PD121 pump head uses
  • Wire-formed Rings
    applications. Round-section rings are for external use on shafts only and are used where the expected load is light. Ring assembly and disassembly tools range from a screwdriver to automatic tools, depending on the application. Carbon spring steel (SAE-1060) is the standard material used in retaining rings
  • Superlative parts crowned at powder-metal competition
    parts have six pocket forms that hold locking pawl and spring elements. The parts sport an ultimate heat-treated tensile strength of 131 kpsi, an impact energy of 12 ft-lb, and a minimum 32 HRC hardness. P/M dropped part cost 20% compared to forged outer races. A complex, 316 stainless-steel
  • Spiral-Wound Rings
    ends. The standard material for spiral-wound retaining rings is carbon spring steel. Some rings are available in other materials such as 302, 316, and 17-7 PH/C stainless steel, NS A286 alloy, beryllium copper, and Inconel X-750. Time and stress greatly influence the allowable operating temperature
  • Stamped Rings
    with a screwdriver or other hand tool. Self-locking rings do not require grooves. They are available for assemblies in which the fastener need not absorb any sizable thrust, but instead serves mainly as a positioning or locking device. Most stamped retaining rings are made of high-carbon spring steel
  • Quick-Action Couplers
    is permissible. They are suitable for vacuums down to 10 >= torr. On pump supply lines, a size should be selected that will not produce about 1.5-psi pressure drop at required flow. A wide variety of seals and materials are available for these couplers: carbon steel, stainless steel, brass, aluminum

  • Materials for Springs
    For spring used at higher temperature than stainless steel springs , iron-base superalloy A286 (JIS SUH660), Nickel-base superalloy or ceramics (silicon nitride) are mainly used.
    The stainless steel rod was electrically connected to a stainless steel spring , on one end, which was also electrically connected to the center pin, on the other end, using a silver-filled epoxy.
