Penn Stainless Products is pleased to announce that Alloy 330 Stainless Steel Plate is now available from 3/16” to ½” thick in 96 x 240 stock plates. Type 330 and nickel alloy 800H are very similar in both chemistry and mechanical properties. Although not necessarily interchangeable any inquiry for 800H should generate 330 as an alternate consideration. The addition of Alloy 330 will complement our existing high temp inventory of 309, 310, 321 and 347. Please call or contact us direct at 513-574-7600 for an up to date quotation on your heat resistant alloy plate requirements.
