Semih Metals is one of the prominent stainless steel manufacturers with graded steel in all kinds of qualities available in the market. The products from this company are delivered to countries and cities of local as well as international significance. Among the outstanding options available is the SS 431 Hollow Bar. They come in various sizes and forms, designed according to individual requirements. The most important advantage of Semih Metals is the exceptional density and strength-to-weight ratio of their products. SS 431 grade has a density of 8 grams per cubic centimeter, much higher than other stainless steel grades available in the market. This high density ensures better quality and strength with abrasion resistance in stainless steel. Semih Metals relies heavily on an inspection team for upholding the highest quality standard.
SS 431 Hollow Bar is a martensitic stainless steel that is both durable and resistant to corrosion. The composition contains nearly 16-18% chromium, 1.25-1.50% molybdenum, and 0.15-0.25% carbon, which provides very high tensile strength with resistance Machine with SS 431 580-750 MPa tensile strength, 415 MPa It has a hard up to 50- 55 HRC including yield strength, 12-15% elongation, Therefore it has good hardness and has a tendency to be suitable for high-stress applications. SS 431 has good resistance to oxidation; it is, therefore an excellent choice for industrial application.
