Martensitic steels - Import export

Only high-quality steel is appropriate for high-quality products which are mostly assembled in the cars of our customers. By using hot forging process, we shape different types of carbon steel, all types of alloy steel and most of the time stainless steel.The Hot forging process and thus the transformation of steels has a number of specific points in its process. We have directed the development of forging into forging stainless steels, as these steels are increasingly present in automotive engines as well as in other segments of the use of forged parts. The advantage of stainless steels is that they are corrosion-resistant, and do not require additional surface protection. Through the hot forging process, we are able to transform both ferritic, martensitic and austenitic stainless steels.

SPIROL’s heavy duty & fatigue resistant Coiled Spring Pins are available in diameters ranging from 1.5mm (.062") up to 20mm (.750"). Standard materials include high carbon steel, 302/304 nickel (austenitic) stainless steel, and 420 chrome (martensitic) stainless steel. Diameters larger than 12mm (.500") are available in 6150 alloy steel. SPIROL invented the Coiled Spring Pin in 1948. Coiled Pins are available in light duty, standard duty and heavy duty to match the required strength and flexibility for each application. A pin too strong for the applied load will not flex and may damage the hole. A pin that is too flexible may fatigue prematurely within the assembly. The Coiled Pin with the optimal balance of strength, flexibility and diameter will result in the prolonged useful life of the assembly.

SS 420 is a heat treatable martensitic chromium stainless steel. Melt practice is controlled to develop a surface nearly free from defects. It provides the best combination of wear resistance and corrosion resistance, and is used in demanding medical accessories, such as high quality surgical instruments. The alloy can be cold formed from the annealed temper.Welding should be accomplished by pre and post heating.Pre-heating at 450° F and post-heated at 1300° F will prevent cracking. The corrosion resistance is optimized in the heat treated temper and assured by passiviation. It is resistant to water and organic materials. Oxidation resistance remains favorable in most applications up through 1200°F.

SS 17/4 PH® is a precipitation hardenable Martensitic stainless steel with high strength, and good corrosion resistance. This makes it perfect for use in metal diaphragms, for both aerospace sensors and burst discs. It is easily heat treated from the annealed temper. The corrosion resistance of the alloy is comparable to SS 302. It is heat treated at 900° F/1 Hour for highest strength. Other thermal treatments can be utilized to provide greater toughness and improved formability. Joining of the alloy is accomplished by the usual methods that are effective for stainless steel. Available Sizes: SS 17/4 PH® is available from Hamilton Precision Metals as strip product in thicknesses from 0.001” to 0.050” (0.0254 mm to 1.27 mm) and widths up to 12.0” (304.8 mm). The material conforms to AMS 5604, ASTM A693 and UNS S17400.

HPM® 455 is a precipitation heat treatable martensitic Stainless Steel. The composition provides a good combination of corrosion resistance and heat treated strength favorable for fatigue applications. The material is well suited for demanding spring devices The alloy has reasonably good forming characteristics in the annealed temper considering that it has a hardness of RC30. A significant radius is useful when bending is necessary in a fabrication. Cold working prior to the precipitation hardening treatment can drive finish strength up to 270,000 PSI (0.2% offset yield strength). The alloy retains a good strength through 800°F (Approx. 70% of room temperature). Resistance to stress – corrosion cracking is optimized by heat treating at 950°F. The overall corrosion resistant to normal atmospheric is equal to SS 430 with no staining. The alloy can be welded by resistance and inert gas shielded techniques. It also is suitable for brazing using a flux when possible.
