As a heat shield, 304 stainless steel handles temperatures up to approximately 870°C (1600°F) in intermittent service, making it suitable for exhaust heat shields, fireplace surrounds, and similar applications.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/details\u003e\n\n  \u003c\/div\u003e\n\n  \u003c!-- ⑥ CTA BAR --\u003e\n  \u003cdiv class=\"hdiy-cta\"\u003e\n    🛒 Select your material, size, and thickness above, then add to cart — ships from our US warehouse.\n  \u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"HomeDIYer","offers":[{"title":"304 Stainless Steel \/ 100×100×1mm \/ 1 pcs","offer_id":52378553319698,"sku":"BEAR012576x1","price":8.69,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 100×100×1.5mm \/ 1 pcs","offer_id":52378553352466,"sku":"BEAR012577x1","price":11.86,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 100×100×2mm \/ 1 pcs","offer_id":52378553385234,"sku":"BEAR012578x1","price":15.12,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 100×100×3mm \/ 1 pcs","offer_id":52378553418002,"sku":"BEAR012579x1","price":21.96,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 100×200×1mm \/ 1 pcs","offer_id":52378553450770,"sku":"BEAR012580x1","price":16.4,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 100×200×1.5mm \/ 1 pcs","offer_id":52378553483538,"sku":"BEAR012581x1","price":24.06,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 100×200×2mm \/ 1 pcs","offer_id":52378553516306,"sku":"BEAR012582x1","price":28.33,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 100×200×3mm \/ 1 pcs","offer_id":52378553549074,"sku":"BEAR012583x1","price":41.7,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 200×200×1mm \/ 1 pcs","offer_id":52378553581842,"sku":"BEAR012584x1","price":28.33,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 200×200×1.5mm \/ 1 pcs","offer_id":52378553614610,"sku":"BEAR012585x1","price":41.7,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 200×200×2mm \/ 1 pcs","offer_id":52378553647378,"sku":"BEAR012586x1","price":55.07,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 200×200×3mm \/ 1 pcs","offer_id":52378553680146,"sku":"BEAR012587x1","price":81.89,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 300×300×1mm \/ 1 pcs","offer_id":52378553712914,"sku":"BEAR012588x1","price":61.47,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 300×300×1.5mm \/ 1 pcs","offer_id":52378553745682,"sku":"BEAR012589x1","price":92.09,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 200×300×1mm \/ 1 pcs","offer_id":52378553778450,"sku":"BEAR012590x1","price":41.7,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 200×300×1.5mm \/ 1 pcs","offer_id":52378553811218,"sku":"BEAR012591x1","price":60.79,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 200×300×2mm \/ 1 pcs","offer_id":52378553843986,"sku":"BEAR012592x1","price":81.89,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.1×300×1000mm \/ 1 pcs","offer_id":52378553876754,"sku":"BEAR012593x1","price":28.63,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.05×300×1000mm \/ 1 pcs","offer_id":52378553909522,"sku":"BEAR012594x1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.15×300×1000mm \/ 1 pcs","offer_id":52378553942290,"sku":"BEAR012595x1","price":40.23,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.2×300×1000mm \/ 1 pcs","offer_id":52378553975058,"sku":"BEAR012596x1","price":47.67,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.3×300×1000mm \/ 1 pcs","offer_id":52378554007826,"sku":"BEAR012597x1","price":68.67,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.4×300×1000mm \/ 1 pcs","offer_id":52378554040594,"sku":"BEAR012598x1","price":92.52,"currency_code":"USD","in_stock":true},{"title":"304 Stainless Steel \/ 0.5×300×1000mm \/ 1 pcs","offer_id":52378554073362,"sku":"BEAR012599x1","price":114.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/8936\/1682\/files\/Picture1of5_7adeac48-c0b3-41e6-b9db-2df2c65c351d.jpg?v=1781600919","url":"https:\/\/homediyer.com\/products\/304-stainless-steel-sheet-metal-plate-005mm-3mm-thick","provider":"HomeDIYer","version":"1.0","type":"link"}
