Metal 410 S.S.The standard of the valve plate industry it is less corrosion resistant than 17-1 Ph S.S. Excellent forthoughness and hardness.
Metal 17-7 Ph.S.S.A patented "superalloy" stainless steel that combines strength, hardness, and elastic properties of the head spring steel with the hardness and corrosion resistance of Austenitic Stainless Steel.
Thermoplastics MP-58Glass-Modified, Heat stabilized Nylon, High Strength, Good Corrosion resistance , and Temperature not to exceed 250°
Thermoplastics MP-MTMid Temurature Nylon, High Strength good for Mid range tempuratures whose best range is between 150° and 285° degrees.
Thermoplastics MP-PeekGlass filled peek®, Used where high strenght to weight ratio is needed with continuous operatration between 285°-480° max temps.
