42、 + 2D ISO 10474 3.16 Classification of gradesCorrosion-resistant stainless steels covered in this part of ISO 16143 are classified according to their structure into austenitic steels, austenitic-ferritic steels, ferritic steels, martensitic steels, or precipitation-hardening steels.7 Requirements7.1

43、 Manufacturing processUnless a special steelmaking process is agreed upon at the time of ordering, the steelmaking process shall be at the discretion of the manufacturer. When he so requests, the purchaser shall be informed what steelmaking process is being used.7.2 Delivery conditionThe products sh

44、all be supplied in the delivery condition agreed upon in the order, by reference to the process route given in Table 3 and, where different alternatives exist, to the treatment conditions given in Tables 4 to 8, 14, and 16 (see also Annex A).7.3 Chemical composition7.3.1 The chemical composition req

45、uirements given in Table 1 apply with respect to the chemical composition of the cast analysis.7.3.2 The product analysis can deviate from the limiting values for the cast analysis given in Table 1 by the values listed in Table 2.

46、.4 Susceptibility to intergranular corrosionReferring to resistance to intergranular corrosion as defined in ISO 3651-2, for ferritic, austenitic, and austenitic-ferritic steels, the specifications in Tables 4, 5, and 6 apply.The susceptibility of stainless steels to intergranular corrosion is depen

47、dent on the type of environment and therefore cannot always be clearly ascertained through standard laboratory tests. The selection of the test or tests to be agreed upon should be based on experience with the use of the selected grade of steel in the intended environment.7.5 Mechanical propertiesTh

48、e mechanical properties at room temperature as specified in Tables 4 to 8 apply for the relevant specified heat-treatment condition. This does not apply to the process route 1U (hot rolled, not heat treated, not descaled). If, by agreement at the time of ordering, the products are to be supplied in

49、a non-heat-treated condition, the mechanical properties specified in Tables 4 to 8 shall be obtainable from reference test pieces which have received the appropriate heat treatment (simulated heat treatment).The values in Tables 9 to 13 apply for the 0,2 %- and 1 %-proof strength at elevated temperatures.For cold-worked products, the 0,2 %-proof strength levels at ambient temperature as specified in Table 14 apply. The available 0,2 %-proof strength levels in the cold-worked condition are in
