These flanges are very durable and resistant to corrosion which is the main reason for these being used in the long-term run in the most critical applications.
What is 17‐4 PH Flanges? Such flanges are made from hardening precipitation martensitic stainless steel, grade 17‐4 PH (UNS S17400, ASTM A693 Type 630). Because of it having very high tensile strength, good hardness, and excellent corrosion resistance, 17‐4 PH Flanges Exporters put it in different markets where it is important that a product lasts even under very harsh conditions. Stainless steel of this grade gives a unique combination of strength and fatigue resistance thus being very suitable for high temperature as well as corrosive works.
The main advantages of 17‐4 PH Flanges include excellent resistance to stress corrosion cracking, very good toughness both in base and weld metals and the capability to resist high temperatures up to 600°F (316°C). Hindco Steel and Alloys is really special among 17‐4 PH Flanges Manufacturers as our products guarantee reduced downtime, increased performance, and extended service life. We are the top 17‐4 PH Flanges Exporters who are chosen by international clients because we always deliver the products that meet ASTM, ASME, DIN, and EN standards the most.
