This document compiles a global list of commonly used heat-resistant steel casting grades, covering HK40, HP40, ASTM A297, ISO 11973, EN material numbers, JIS SCH series, and GB/T 8492, and provides reference alternative grades and disclaimers.

There is no fixed minimum wall thickness for precision casting that applies to all parts. This article explains how material, flow length, part size, and structure affect wall thickness, and outlines design considerations for fillets, slots, bosses, ribs, and thickness transitions.

Precision casting of stainless steel valve bodies requires simultaneous consideration of the medium and pressure, flow channel structure, wall thickness transition, CNC machining of the sealing surface, and pressure testing. This article explains the key points of valve body manufacturing from drawing review to finished product inspection.

Why do stainless steel casting prices vary so much? This article breaks down nine price factors, including material, structure, unit weight, quantity, mold, CNC machining, inspection, and delivery time, and provides a list of casting inquiry materials that can be used directly.

Machining allowances in precision casting are not fixed values. This article explains how to determine the machining surfaces and allowances for stainless steel castings from blank to CNC finished product, starting from machining datum, casting structure, dimensional tolerances, deformation risks, and clamping methods.

This document provides a comparison table of common stainless steel casting grades, including the correspondences of materials such as 304, 316, 304L, 316L, CF8, CF8M, CF3, CF3M, 1.4308, 1.4408, SCS13, SCS14A, 2205, and 2507 in ASTM, AISI, EN, DIN, JIS, and Chinese GB standards.

CF8, CF8M, CF3, and CF3M are common casting grades in stainless steel castings, corresponding to 304, 316, 304L, and 316L stainless steel, respectively. This article compiles a comparison table of stainless steel casting grades and explains the performance differences and application scenarios of different materials.

304, 304L, 316, and 316L are commonly used materials in stainless steel castings. This article analyzes how to select different stainless steel precision casting materials from the perspectives of corrosion resistance, weldability, cost, application scenarios, and casting processing.

CF8 corresponds to 304 stainless steel, while CF8M corresponds to 316 stainless steel. This article details the differences between CF8 and CF8M in terms of corrosion resistance, mechanical properties, applications, and cost, helping you choose the appropriate stainless steel precision casting material.
