314耐热钢板

{"faq": [{"answer": "是同一种材料。314为通俗叫法，强调25Cr-20Ni基础上提高硅含量至约2%，标准牌号为310Si2，国标06Cr25Ni20Si2，UNS编号S31009。", "question": "314和310Si2是同一种材料吗？"}, {"answer": "适合渗碳炉、碳氮共渗炉、高温气氛炉等含碳气氛环境，高硅含量形成致密氧化膜阻止碳原子渗入；普通高温氧化环境选用2520（310S）即可。", "question": "314适合用在什么环境？"}], "temp": "700~1200℃", "grade": "314", "features": ["高硅含量", "抗渗碳", "耐高温"], "packaging": "标准出口包装：内衬塑料薄膜防潮，外用钢带捆扎，木托盘或木箱包装。可根据客户要求定制包装方式。", "standards": {"en": "X12CrNiSi25-21", "gb": "06Cr25Ni20Si2 (GB/T 1221)", "jis": "-", "uns": "S31009", "wnr": "1.4846", "astm": "A240/A240M 310Si2"}, "thickness": "0.5~60mm", "priceRange": "30,000 - 38,000", "stockSpecs": [{"width": "1000/1219mm", "length": "C（卷）", "thickness": "0.5~1.0mm"}, {"width": "1000/1219/1500mm", "length": "C（卷）/2000/2438mm", "thickness": "1.0~3.0mm"}, {"width": "1219/1500mm", "length": "2000/2438/6000mm", "thickness": "3.0~6.0mm"}, {"width": "1500/1800/2000mm", "length": "6000mm", "thickness": "6.0~20mm"}, {"width": "1500/1800/2000mm", "length": "6000mm", "thickness": "20~60mm"}], "application": "渗碳炉、高温气氛炉、热处理设备", "description": "314是国内对25Cr-20Ni-2Si高硅耐热不锈钢的通俗叫法，对应标准牌号为310Si2、国标06Cr25Ni20Si2、欧标X12CrNiSi25-21、德标1.4846、UNS S31009。硅含量提高到1.50%~2.50%，在高温含碳气氛中形成致密氧化膜，抗渗碳性能明显优于2520，适用于渗碳炉、碳氮共渗炉、高温气氛炉与锂电正极材料烧结炉等工况。", "deliveryTime": "常规规格现货3-5天发货，非标规格定制10-20天", "certifications": ["ISO 9001:2015", "SGS 质量认证", "TUV 认证", "PED 认证"], "surfaceTreatments": ["No.1（热轧退火酸洗）", "2B（冷轧退火酸洗）"], "physicalProperties": {"density": "7.98 g/cm³", "meltingPoint": "1398~1454℃", "specificHeat": "500 J/kg·K", "elasticModulus": "200 GPa", "thermalExpansion": "15.9 ×10⁻⁶/℃ (0~100℃)", "thermalConductivity": "14.2 W/m·K (100℃)", "electricalResistivity": "0.78 μΩ·m"}, "chemicalComposition": [{"content": "≤0.08%", "element": "C（碳）"}, {"content": "1.50~2.50%", "element": "Si（硅）"}, {"content": "≤2.00%", "element": "Mn（锰）"}, {"content": "24.00~26.00%", "element": "Cr（铬）"}, {"content": "19.00~22.00%", "element": "Ni（镍）"}, {"content": "≤0.030%", "element": "S（硫）"}, {"content": "≤0.035%", "element": "P（磷）"}], "applicationScenarios": [{"industry": "热处理", "equipment": "渗碳炉、碳氮共渗炉", "description": "高硅含量有效抵抗碳渗透，延长炉体寿命"}, {"industry": "化工行业", "equipment": "高温反应器、裂解炉", "description": "耐渗碳腐蚀，适合含碳气氛环境"}, {"industry": "新能源", "equipment": "锂电池正极材料烧结炉", "description": "高温烧结环境下抗渗碳、抗腐蚀，保障产品纯度"}, {"industry": "环保设备", "equipment": "危废焚烧炉、热解气化炉", "description": "耐高温渗碳气氛腐蚀，适用于固废处理高温设备"}], "mechanicalProperties": [{"value": "≥520", "property": "抗拉强度（MPa）"}, {"value": "≥205", "property": "屈服强度（MPa）"}, {"value": "≥40", "property": "延伸率（%）"}, {"value": "≤187", "property": "硬度（HB）"}], "processingPerformance": {"weldMethod": "TIG焊、MIG焊、手工电弧焊", "formability": "良好，可进行冷弯、热弯等加工", "weldability": "良好，需注意硅对焊接的影响", "heatTreatment": "固溶处理 1040~1150℃ 水冷", "machinability": "中等，硅含量较高时加工难度略增"}}
