Bisalloy Steels Structural 80PV Thickness 6-<30 mm Product Information -:- For detailed product information, please contact sales. -: ### **Product Name:** Bisalloy Steels Structural 80PV (80PVQ) **Classification:** High-Strength, Quenched and Tempered Alloy Steel Plate for Pressure Vessel Applications --- ### **1. Overview** Bisalloy 80PV is a premium, **quenched and tempered (Q&T) alloy steel plate** specifically engineered for high-performance pressure vessel and structural applications where exceptional strength-to-weight ratio and superior toughness are critical. With a **minimum yield strength of 690 MPa (100 ksi)**, it belongs to the high-strength end of pressure vessel steels. The "PV" designation indicates its suitability for **pressure vessel** construction, with enhanced internal cleanliness, strict chemical control, and guaranteed through-thickness properties. Its quenched and tempered microstructure provides an outstanding combination of high strength, good weldability (with proper procedure), and excellent low-temperature impact resistance, enabling the design of lighter, more efficient, and highly reliable equipment. ### **2. Chemical Composition (Weight %, ladle analysis)** Composition is tightly controlled by Bisalloy to achieve the optimal balance of strength, toughness, and weldability. | Element | Minimum (%) | Maximum (%) | Notes | |---------|------------|------------|-------| | **Carbon (C)** | - | 0.16 | Low carbon content is key to ensuring good weldability and toughness at high strength levels. | | **Manganese (Mn)** | 0.80 | 1.60 | Provides solid solution strengthening and hardenability. | | **Silicon (Si)** | 0.15 | 0.50 | Deoxidizer and strengthening element. | | **Phosphorus (P)** | - | 0.020 | Very low to maximize toughness. | | **Sulfur (S)** | - | 0.010 | Very low to improve weldability, formability, and through-thickness properties. | | **Chromium (Cr)** | 0.30 | 1.00 | Enhances hardenability, strength, and tempering resistance. | | **Molybdenum (Mo)** | 0.10 | 0.30 | Increases hardenability and strength, and improves high-temperature strength. | | **Boron (B)** | *Optional* | *Optional* | May be added in minute quantities to significantly boost hardenability. | | **Carbon Equivalent (CEV/CET)** | - | ~0.50-0.55 (Typ.) | Indicates weldability; requires strict procedure controls (preheat, low-H₂ consumables). | **Note:** The exact proprietary chemistry may vary. The steel is fully killed and fine-grained. ### **3. Physical & Mechanical Properties** *Properties are for quenched and tempered condition. Values specified for thickness range 6 mm to <30 mm.* **Mechanical Properties (Guaranteed Minimum):** * **Yield Strength (Rp0.2, min):** 690 MPa (100 ksi) * **Tensile Strength (Rm):** 770 - 940 MPa (112 - 136 ksi) * **Elongation (A, min):** 14% (on gauge length 5.65√S₀) * **Impact Energy (Charpy V-Notch):** * **Test Temperature:** Typically **-40°C (-40°F)** or lower (e.g., -50°C, -60°C) can be specified. * **Minimum Average (Longitudinal):** **40 J** at specified temperature. * **Minimum Single Value:** Typically 32 J. * **Hardness (typical):** 240 - 290 HBW **Through-Thickness Properties (Z-Direction):** * **Reduction of Area (Z, min):** Commonly ≥ 35% per customer specification, demonstrating excellent resistance to lamellar tearing in highly restrained welded joints. **Physical Properties (Typical):** * **Density:** 7.85 g/cm³ * **Modulus of Elasticity:** 210 GPa * **Poisson's Ratio:** 0.3 ### **4. Key Characteristics** * **Exceptional Strength-to-Weight Ratio:** Enables significant reductions in plate thickness and equipment weight compared to conventional steels (e.g., A516 Gr.70), leading to material savings, lower transport costs, and potentially smaller foundations. * **Superior Low-Temperature Toughness:** The Q&T process delivers excellent impact properties at temperatures as low as -60°C, making it ideal for cryogenic and cold-climate applications. * **Good Weldability (with Controlled Procedures):** Despite its high strength, the low carbon content and fine-tuned alloying allow for reliable welding. However, it demands strict adherence to qualified Welding Procedure Specifications (WPS). * **Excellent Fatigue Resistance:** The clean, homogeneous Q&T microstructure provides enhanced resistance to cyclic loading. * **Guaranteed Through-Thickness Properties:** Critical for thick plates and highly constrained T-joints in pressure vessels, minimizing the risk of lamellar tearing. ### **5. Product Application** Bisalloy 80PV is specified for demanding pressure equipment and critical structures where performance and reliability are paramount: * **High-Pressure & Cryogenic Pressure Vessels:** Reactors, separators, and storage tanks for LNG, LPG, ammonia, and hydrogen. * **Mobile Pressure Equipment:** Skids, transportable modules, and ISO containers where weight is a major constraint. * **Mining & Mineral Processing:** High-wear, high-stress components in thickeners, flotation cells, and slurry tanks. * **Hydraulic & Pneumatic Accumulators:** For ultra-high-pressure fluid power systems. * **Critical Structural Components:** In offshore platforms, crane booms, and other heavy machinery where high strength and toughness are required. ### **6. International Standards & Specifications** Bisalloy 80PV is produced to meet or exceed several international standards and is often supplied to proprietary Bisalloy specifications. | Region / System | Standard & Designation | Scope / Notes | |----------------|----------------------|---------------| | **Bisalloy Specification** | **Bisalloy 80PV** | Proprietary mill specification with guaranteed properties. | | **European Union** | **EN 10028-6** | Pressure vessel steel plates, Q&T condition. Comparable to grades like **S690Q/QL/QL1**. | | **International / ISO** | **ISO 9328-6** | Similar to EN 10028-6. **Grade S690Q** is a close equivalent. | | **USA / ASTM** | **ASTM A517 / A832** | Grade H or similar quenched & tempered alloy steels for pressure vessels offer comparable strength, but chemistry may differ. | | **Australia / NZ** | **AS/NZS 3678** | Grade 800, though this is a structural rather than pressure vessel grade. | | **Japan** | **JIS G3126 SQV 570A/B** | High yield strength steel plates for pressure vessels with similar strength class. | ### **7. Available Forms & Processing** * **Standard Forms:** Supplied as **plates**. Thickness range: **6 mm to <30 mm** (as specified; also available in thicker sections). * **Condition:** **Quenched and Tempered (Q/T)**. * **Fabrication:** * **Welding:** **Requires a qualified WPS.** Key practices include: * Use of low-hydrogen, high-toughness consumables (e.g., matching or undermatching). * Mandatory pre-heat (typically 100-150°C minimum). * Strict control of heat input and interpass temperature (usually <250°C). * Strong recommendation for Post-Weld Heat Treatment (PWHT). * **Forming:** Good cold forming properties for moderate bends. Hot forming is possible but requires temperature control to avoid affecting the Q&T microstructure. * **Cutting:** All thermal cutting methods (plasma, laser, oxy-fuel) are suitable. For flame-cut edges, light grinding may be recommended to remove the heat-affected layer. ### **8.
