I currently use 17-7 PH stainless which is hardened to condition CH after forming. raw matl is .1.75"X .12" X .008". Its main usage after hardening is silicon wafer retainer where it's contantly cycled up and down to putin and remove wafer after 40-60 sec process at 400C temp. At this high temperature this part seemed to deform after a a couple of hundred wafer which is what it was designed for in the first place. THere is a proposal to go to a different material to increase lifeline of this part. My question is..... can 321 SST be a plugin replacement. I know this has a higher temp rating but how about its forming characteristics, will it have spring properties, and wont become brittle after prolonged exposure to 400C.

An ice-box is built of wood 1.75 cm thick, lined with cork 3 cm thick. If in the steady state the temperature of the inner surface of the cork is 0 ºC and that of the outer surface of wood is 12 ºC, what is the temperature of the wood-cork interface? The thermal conductivities of wood and cork are 0.2 W/m-K and 0.04 W/m-K respectively

hii..i am doin a project called Forecaster..wat it does is it asks user to enter a zip code..then it establishes urlconnection with a weather website n fetches data n data is converted into graphical representation..but it doesnt show any output..i am not able it figure out the reason..can u plzzzz help me out..i am givin u code import java.io.*; import java.awt.*; import java.net.*; import java.awt.image.*; import java.awt.event.*; public class Forecast extends Frame { OkCancelDialog textDialog; BufferedImage image = null; public static void main(String[] args) { new Forecast(); } public Forecast() { String zip =""; File zipFile = new File("zip.txt"); String hiTemperature[] = new String[4]; String loTemperature[] = new String[4]; try { if(zipFile.exists()){ FileReader filereader = new FileReader("zip.txt"); BufferedReader bufferedreader = new BufferedReader(filereader); zip = bufferedreader.readLine(); } else { textDialog = new OkCancelDialog(this, "Enter your five-digit zip code", true); textDialog.setVisible(true); zip = textDialog.data.trim(); FileOutputStream fileoutputstream = new FileOutputStream("zip.txt"); fileoutputstream.write(zip.getBytes()); } int character; URL url = new URL ("http://www.srh.noaa.gov/zipcity.php?inputstring=" + zip); URLConnection urlconnection = url.openConnection(); InputStream in = urlconnection.getInputStream(); String input = ""; String hiSearch; String loSearch; String inchar; char[] cc = new char[1]; while ((character = in.read()) != -1) { char z = (char)character; cc[0] = z; inchar = new String(cc); input += inchar; } in.close(); if(input.indexOf("Hi ") >= 0){ hiSearch = "Hi "; } else{ hiSearch= "Hi: "; } int currentPosition = 0; for(int loopIndex = 0; loopIndex < 4; loopIndex++){ int location = input.indexOf(hiSearch, currentPosition); int end = input.indexOf("°", location); hiTemperature[loopIndex] = input.substring(location + hiSearch.length(), end); currentPosition = end + 1; } if(input.indexOf("Lo ") >= 0){ loSearch = "Lo "; } else{ loSearch= "Lo: "; } currentPosition = 0; for(int loopIndex = 0; loopIndex < 4; loopIndex++){ int location = input.indexOf(loSearch, currentPosition); int end = input.indexOf("°", location); loTemperature[loopIndex] = input.substring(location + loSearch.length(), end); currentPosition = end + 1; } boolean evening = false; if(input.indexOf(loSearch) < input.indexOf(hiSearch)){ evening = true; hiTemperature[3] = hiTemperature[2]; hiTemperature[2] = hiTemperature[1]; hiTemperature[1] = hiTemperature[0]; } image = new BufferedImage(225, 201, BufferedImage.TYPE_INT_RGB); Graphics2D g = image.createGraphics(); g.setColor(Color.white); g.fillRect(0, 0, 224, 201); g.setColor(Color.gray); for(int loopIndex = 0; loopIndex < 21; loopIndex++){ g.drawLine(25, loopIndex * 10, 224, loopIndex * 10); g.drawLine(loopIndex * 10 + 25, 0, loopIndex * 10 + 25, 199); } g.setColor(Color.blue); Font font = new Font("Courier", Font.PLAIN, 18); g.setFont(font); for(int loopIndex = 20; loopIndex < 200; loopIndex += 20){ g.drawString(String.valueOf(100 - loopIndex / 2), 0, loopIndex + 5); } g.setColor(Color.red); if(!evening){ g.drawOval(65 - 4, 200 - (Integer.parseInt( hiTemperature[0]) * 2) - 4, 8, 8); } g.drawOval(105 - 4, 200 - (Integer.parseInt( hiTemperature[1]) * 2) - 4, 8, 8); g.drawOval(145 - 4, 200 - (Integer.parseInt( hiTemperature[2]) * 2) - 4, 8, 8); g.drawOval(185 - 4, 200 - (Integer.parseInt( hiTemperature[3]) * 2) - 4, 8, 8); if(!evening){ g.drawLine(65, 200 - (Integer.parseInt( hiTemperature[0]) * 2), 105, 200 - (Integer.parseInt(hiTemperature[1]) * 2)); } g.drawLine(105, 200 - (Integer.parseInt(hiTemperature[1]) * 2), 145, 200 - (Integer.parseInt(hiTemperature[2]) * 2)); g.drawLine(145, 200 - (Integer.parseInt(hiTemperature[2]) * 2), 185, 200 - (Integer.parseInt(hiTemperature[3]) * 2)); g.setColor(Color.blue); g.drawOval(65 - 4, 200 - (Integer.parseInt( loTemperature[0]) * 2) - 4, 8, 8); g.drawOval(105 - 4, 200 - (Integer.parseInt( loTemperature[1]) * 2) - 4, 8, 8); g.drawOval(145 - 4, 200 - (Integer.parseInt( loTemperature[2]) * 2) - 4, 8, 8); g.drawOval(185 - 4, 200 - (Integer.parseInt( loTemperature[3]) * 2) - 4, 8, 8); g.drawLine(65, 200 - (Integer.parseInt(loTemperature[0]) * 2), 105, 200 - (Integer.parseInt(loTemperature[1]) * 2)); g.drawLine(105, 200 - (Integer.parseInt(loTemperature[1]) * 2), 145, 200 - (Integer.parseInt(loTemperature[2]) * 2)); g.drawLine(145, 200 - (Integer.parseInt(loTemperature[2]) * 2), 185, 200 - (Integer.parseInt(loTemperature[3]) * 2)); g.setColor(Color.white); g.fillRect(55, 160, 140, 30); g.setColor(Color.blue); g.drawRect(55, 160, 140, 30); font = new Font("Courier", Font.PLAIN, 12); g.setFont(font); g.drawString("Four-Day Forecast", 65, 172); font = new Font("Courier", Font.PLAIN, 9); g.setFont(font); g.drawString("Source: Nat.
