Stainless Steel Square Bar-13-8 PH

According to the production process, stainless steel rods can be divided into three types: hot rolling, forging and cold drawing. The specification of hot rolled stainless steel round bar is 5.5-250 mm. Among them: 5.5-25mm small stainless steel round bars are mostly supplied in bundles of straight strips, which are often used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25mm are mainly used for the manufacture of mechanical parts or as seamless steel pipe billets .

PH 13-8 Mo is a martensitic precipitation hardening stainless steel that is desired due to its corrosion resistance, excellent toughness, excellent strength and high hardness. Tight chemical composition control, low carbon content and vacuum melting achieve good transverse toughness. The alloy is produced by vacuum induction melting (VIM) followed by electroslag remelting (ESR). This fusion method promotes excellent macro and micro cleanliness and tight composition control. The strengthening mechanism (precipitation hardening in the martensitic matrix) enables uniform strengthening in thicker sections. Strength and ductility levels can be adapted to the application by varying the aging temperature.
PH 13-8 Mo has a martensitic structure under solution annealing conditions, and is further strengthened by lower temperature heat treatment, thereby precipitation strengthening phase in the alloy. As with the 17-4 PH alloy, only one heat treatment is required in the temperature range of 950°F (510°C) to 1150°F (620°C), depending on the combination of strength and toughness desired. Heat treatment through this step can yield a wide range of properties. Highest strength is achieved by heat treating at temperatures around 950°F (510°C).
 13-8 MO Rods is a martensitic age-hardening / precipitation stainless steel which is quite accomplished of elevated strength and hardness together with good levels of resistance to both stress-corrosion cracking and general corrosion. In addition, these PH 13-8 MO Alloy Round Bars exhibits excellent toughness and ductility in large sections in both the transverse and longitudinal directions.
