二相ステンレス鋼の世界市場規模：製品タイプ別、形状別、最終用途産業別、地域範囲別、予測

二相ステンレス鋼の市場規模と予測

二相ステンレス鋼市場規模は、2024年に29億1,000万米ドルと評価され、2026年から2032年にかけて4.20%のCAGRで成長し、2032年には40億4,000万米ドルに達すると予測されます。

二相ステンレス鋼はステンレス鋼の一種で、フェライト相とオーステナイト相という2つの相を組み合わせた特異な微細構造によって区別されます。フェライト相は鉄の磁性相で、強度と応力への耐性を向上させるが、オーステナイト相は非磁性相で、靭性と延性を向上させる。

二相ステンレス鋼は、様々な分野で非常に適応性が高く、価値のあるユニークな性質を持っています。二相ステンレス鋼は、過酷な環境に耐え、塩素などの腐食性物質による腐食に耐えるため、石油・ガス産業の機器やパイプラインに使用されています。

二相ステンレス鋼は、耐久性、強度、耐食性に対するニーズの高まりに対応する優れた特性を持っており、今後、さまざまな産業で使用量が飛躍的に増加すると予想されます。企業がより経済的で耐久性のある材料を求める中、二相ステンレス鋼は、過酷な環境にも耐えるという点で際立っています。

二相ステンレス鋼の世界市場力学

二相ステンレス鋼の世界市場を形成している主な市場力学は以下の通りである：

主な市場促進要因

優れた耐食性：二相ステンレス鋼市場の主な促進要因の1つは、耐食性の高さです。二相ステンレス鋼は、フェライト相とオーステナイト相の二相微細構造を持つため、孔食、すきま腐食、応力腐食割れなど幅広い腐食に耐性を持っています。そのため、強い化学薬品や海水と頻繁に接触する状況に最適です。

高い強度と耐久性：二相ステンレス鋼は、標準的なオーステナイト系ステンレス鋼やフェライト系ステンレス鋼よりも高い強度を有します。フェライト相とオーステナイト相の組み合わせにより、引張強度が向上するため、強度を犠牲にすることなく、断面を小さくしたり、構造を軽くすることができます。

費用対効果：二相ステンレス鋼は、ニッケル基合金よりも安価な材料です。当初は従来のステンレス鋼より高価だが、耐食性と強度に優れているため、交換やメンテナンスの回数が少なくて済みます。

主な課題

特定環境下での腐食：二相ステンレス鋼は、さまざまな種類の腐食に対して優れた耐性を持つことで知られているが、すべての腐食環境に対応できるわけではないです。強硫酸を含むような強酸性または侵食性の環境では、二相ステンレス鋼は他の特殊合金よりも性能が低下する可能性があります。

溶接の難しさ：二相ステンレス鋼の特異なミクロ組織は、溶接を困難にします。不要な相転移や溶接継手の弱体化を避けるため、溶接時にフェライト相とオーステナイト相の組み合わせを注意深く制御する必要があります。溶接が適切でない場合、二相ステンレス鋼は機械的特性を失い、脆化する可能性があります。

加工および製造：二相ステンレス鋼は、他のステンレス鋼よりも加工が難しい場合があります。二相ステンレス鋼の硬度と強度は、工具の過度な摩耗と加工費の増加を引き起こす可能性があります。二相ステンレス鋼の部品加工には、その過酷で高強度な特性を扱うための専門的な設備と技術が必要になることが多いです。

主要動向

石油・ガス産業における需要の増加：高強度で耐食性に優れる二相ステンレス鋼は、石油・ガス産業をはじめとするさまざまな産業で使用されるようになると予想されます。また、海上や陸上の過酷な環境にも耐えることができるため、パイプライン、バルブ、ポンプ、その他の機器への応用が強化されます。

建設・インフラ部門からの需要拡大：標準的なオーステナイト系およびフェライト系ステンレス鋼と比較すると、二相ステンレス鋼の構造的完全性は、建築物や橋梁への適用を高めています。加えて、性能を維持したまま厚さを薄くできる二相ステンレス鋼の費用対効果は、予測期間中に売上を急増させる可能性が高いです。

鋼種と規格の進歩：より高い耐食性と強度に対する需要の高まりが、新鋼種の開発を後押ししています。また、二相ステンレス鋼鋼種の標準化により、世界市場で二相ステンレス鋼鋼種が広く受け入れられています。

持続可能性と環境問題：世界の持続可能性の重視の高まりにより、リサイクル可能な鋼材や、耐久性があり、交換が最小限に抑えられる鋼材が求められています。強度と重量の比は、特に輸送や建設用途において、エネルギー効率に貢献する軽量構造を可能にします。

活況を呈する海水淡水化プラント海水淡水化プラントの配管や熱交換器では、塩化物や海水の腐食に対する優れた耐性が求められ、二相ステンレス鋼市場が活性化しています。

Duplex Stainless Steel Market Size and Forecast

Duplex Stainless Steel Market size was valued at USD 2.91 Billion in 2024 and is projected to reach USD 4.04 Billion by 2032, growing at a CAGR of 4.20% from 2026 to 2032.

Duplex stainless steel is a type of stainless steel distinguished by its peculiar microstructure which combines two separate phases: ferrite and austenite. Ferrite is a magnetic form of iron that increases strength and resistance to stress, whereas austenite is a nonmagnetic form that improves toughness and ductility.

Duplex stainless steel has unique qualities that make it extremely adaptable and valuable in a variety of sectors. Duplex stainless steel is used in the oil and gas industry for equipment and pipelines because it can withstand harsh environments and resist corrosion from chlorine and other corrosive substances.

The future use of duplex stainless steel is predicted to increase dramatically due to its remarkable qualities that meet the growing needs for durability, strength, and corrosion resistance in a variety of industries. As businesses seek more economical and durable materials, duplex stainless steel stands out for its ability to tolerate hostile environments.

Global Duplex Stainless Steel Market Dynamics

The key market dynamics that are shaping the global duplex stainless steel market include:

Key Market Drivers:

Superior Corrosion Resistance: One of the primary drivers of the duplex stainless steel market is its high corrosion resistance. Duplex stainless steel's dual-phase microstructure of ferrite and austenite makes it resistant to a wide range of corrosion including pitting, crevice, and stress corrosion cracking. This makes it ideal for situations with frequent contact with strong chemicals or the ocean.

High Strength and Durability: Duplex stainless steel has a higher strength than standard austenitic and ferritic stainless steels. The combination of ferrite and austenite phases results in increased tensile strength allowing for smaller sections and lighter structures without sacrificing strength.

Cost-Effectiveness: Duplex stainless steel is a less expensive material than nickel-based alloys. While it is more expensive than conventional stainless steel at first, its better corrosion resistance and strength mean fewer replacements and maintenance are required.

Key Challenges:

Corrosion in Specific Environments: Although duplex stainless steel is known for its outstanding resistance to various types of corrosion, it is not impervious to all corrosive environments. In very acidic or aggressive situations such as those containing strong sulfuric acid, duplex stainless steel may perform worse than other specialty alloys.

Welding Difficulties: The unusual microstructure of duplex stainless steel makes welding difficult. To avoid unwanted phase transitions or weld joint weakening the combination of ferrite and austenite phases must be carefully controlled during welding. If not properly welded, duplex stainless steel might lose mechanical qualities or potentially become embrittled.

Machining and Fabrication: Duplex stainless steel might be more difficult to deal with than other forms of stainless steel. Its hardness and strength might cause excessive tool wear and higher machining expenses. Fabricating components from duplex stainless steel frequently necessitates specialist equipment and techniques to handle its harsh, high-strength properties.

Key Trends:

Increasing Demand in Oil and Gas Industry: Its high strength and excellent corrosion resistance is projected to enhance its use across various industries, especially oil and gas industry. Also, its ability to withstand harsh offshore and onshore environments enhancing its application in pipelines, valves, pumps, and other equipment.

Growing Demand from Construction and Infrastructure Sector: When compared to standard austenitic and ferritic stainless steels the structural integrity of duplex stainless steel is upsurging its application compared in buildings and bridges. In addition to this, the cost-effectiveness of this steel by reducing the thickness while maintaining the performance is likely to skyrockets its sales over the forecast period.

Advancements in Grades and Standards: Growing demand for higher corrosion resistance and strength is supporting ongoing development of newer grades. Along with this, the standardization of duplex stainless steel grades is widening its acceptance across the global market.

Sustainability and Environmental Concerns: Growing global emphasis on sustainability is demanding recyclable steel as well as ones with durability and minimal replaceability. Its strength-to-weight ratio allows for lighter constructions, which can contribute to energy efficiency, particularly in transportation and construction applications.

Booming Desalination Plants: The need for excellent resistance to chloride and seawater corrosion in desalination plants for use in pipes and heat exchangers is bolstering the duplex stainless steel market.
