When it comes to choosing high-performance stainless steel, Super Duplex 32750 and 32760 are two names that often come up. At Mehta Metals, the largest exporter & supplier of premium-rated stainless steel products, we often receive queries asking about the key distinctions between these two grades.
In this blog, we’ll break it down for you in painless terms, highlighting the chemical, mechanical, and application-built nuances. Whether you are sourcing a super duplex bar or need a super duplex pipe & tube specification, this essay will help you develop an informed choice.
What is Super Duplex Stainless Steel?
Super Duplex Stainless Steel is a class of stainless steel that contains a mixture of austenite & ferrite phases. This gives it enhanced properties, corrosion resistance, and stress corrosion cracking resistance compared to standard duplex or continuous stainless steel.
Super Duplex 32750 – Overview
Chemical Composition and Characteristics
Super Duplex or UNS S32750 is known for its high chromium (24-26%), molybdenum (3-5%), and nitrogen content.
These elements contribute to terrific resistance opposition:
- Pitting and crevice corrosion
- Chloride stress corrosion cracking
- Diminishment and fatigue
This makes super duplex UNS 32750 ideal for offshore platforms, chemical tanks, and paper mills.
Key Applications
- Desalination plants
- Oil and gas industry
- Marine environments
- Heat exchangers
Improvements of UNS S32750
- Twice the wealth of 300 series stainless steel
- Wonderful weldability
- Long service life in extreme environments
Super Duplex 32760 – Overview
Chemical Composition and Functions
Super Duplex UNS S32760 has much more similarity to 32750, & contains barely enough more tungsten and copper. This slight variation amplifies its corrosion resistance in highly acidic & chloride-rich environments.
Applications
- Subsea equipment
- Seawater handling systems
- Pollution control equipment
- Chemical operation industries
Gains of Super Duplex UNS S32760
- Higher resistance to sulphide stress cracking
- Higher-quality consequence resource
- Improved performance under higher temperatures
Super Duplex 32750 vs Super Duplex 32760 – The Core Differences
| Property | Super Duplex UNS S32750 | Super Duplex UNS S32760 |
| UNS Number | UNS S32750 | UNS S32760 |
| Copper Content | Lower | Higher |
| Tungsten Content | Lower | Higher |
| Corrosion Resistance | Excellent | Slightly Superior |
| Common Applications | Marine, Desalination | Oil, Gas, High-Stress |
| Availability | Widely Available | Available, Specialized |
But similarly, 32760 performs narrowly better in combative & high-pressure environments, while 32750 remains a robust, versatile option for most of the applications. Regardless, there might be a question in your mind: Is Super Duplex 32760 better than 32750 for my application? & if it is, then where can you buy the best quality super duplex bars?
Choosing the Proper Status for Your Project
If your project involves excessive temperatures, high pressure, or high chloride tiers (like offshore or underwater construction), super duplex UNS S32760 may be your greatest stake.
Anyway, if you’re working in a moderately corrosive habitat and need cost-effective performance, UNS S32750 can deliver impressive value.
